The Cutest Mama & Baby Crochet Whale You’ll Ever Make 🐋

There is something undeniably magical about making a set. The moment you finish a tiny little baby whale and place it next to its mama, something shifts in your chest — a warmth that no other craft quite delivers the way crochet does. This mama and baby crochet whale pattern is one of those projects that checks every single box: it is beginner-friendly enough to feel approachable, detailed enough to feel satisfying, and the finished result is so absurdly cute that you will want to make multiples before you even finish your first set.

Whether you are making these for a baby shower, a nursery decoration, a gift for someone who loves ocean-themed everything, or simply because you needed an excuse to buy that gorgeous blue yarn sitting in your stash, this project is for you. In this post, we are going to walk through everything you need to know — materials, stitches, sizing, tips, and the full pattern for both mama and baby whale. By the end, you will have a pair of soft, squishy, show-stopping whales ready to display or gift with pride.

Why Everyone Is Obsessed With Crochet Whales Right Now

Crochet whales have been having a moment for a few years now, and it is easy to understand why. They are simple in silhouette — that beautiful rounded body, the iconic tail fluke, the little side fins — which makes them a satisfying amigurumi project for crafters who are still building confidence with three-dimensional shapes. At the same time, they leave plenty of room for creativity. You can make them realistic in blues and grays, or go full fantasy mode with pastel pink bodies and gold safety eyes. You can add blushing cheeks, a sweet embroidered smile, a little bow, or even a tiny crown.

The mama and baby pairing adds a storytelling element that makes these whales especially popular as baby shower gifts and nursery décor. There is an emotional resonance to a big soft mama whale and her tiny companion that makes people stop and say “oh my goodness” in a way that solo toys sometimes don’t achieve. If you have ever wanted to crochet something that people will talk about, this is your project.

Materials You Will Need

Before you dive into the pattern, let us get your supplies sorted. The good news is that you do not need anything fancy or expensive to make these whales look amazing.

For yarn, you will want a soft worsted weight yarn (size 4) in your chosen body color. Classic whale colors include navy blue, cerulean, slate gray, dusty teal, and lavender, but truly any color you love will work beautifully. You will also want a small amount of white yarn for the belly panel on the mama whale, and an optional contrast color if you want to add any accent details. For the baby, the same main color yarn is all you need.

For the hook, a 3.5mm or 4.0mm crochet hook works best with worsted weight yarn for amigurumi, because you want a tighter gauge that prevents the stuffing from showing through. If you tend to crochet loosely, go with a 3.5mm. If you tend to crochet tightly, a 4.0mm will keep things from getting too stiff.

You will also need polyfill stuffing, two pairs of 9mm black safety eyes (or 12mm for the mama if you prefer a larger look), a yarn needle for sewing pieces together, stitch markers to keep track of your rounds, and scissors. Optional but adorable additions include pink embroidery floss or yarn for blushing cheeks, black embroidery floss for a smile, and small ribbon or buttons for decorative details.

Key Stitches and Abbreviations

This pattern uses US crochet terminology throughout. Here is a quick reference for the stitches you will encounter:

MR — Magic ring (also called a magic circle)
ch — Chain
sl st — Slip stitch
sc — Single crochet
inc — Increase (two single crochets in the same stitch)
dec — Invisible decrease (insert hook through the front loops only of the next two stitches, yarn over and pull through both loops, yarn over and pull through the remaining two loops)
BLO — Back loops only
FLO — Front loops only

All rounds are worked in a continuous spiral unless otherwise noted. Do not join rounds unless the pattern specifies a join.

Sizing and Gauge

With the recommended yarn and hook size, the finished mama whale will measure approximately 7 to 8 inches long from nose to tail and about 4 inches tall. The baby whale will measure approximately 4 inches long and about 2.5 inches tall. These are satisfying, substantial sizes — not too tiny to sew, not so large that they take forever to finish.

If you want to adjust the sizing, you can simply go up or down in yarn weight. Using a chunky yarn with a 5.0mm hook will give you a larger, plushier whale perfect for younger children. Using a DK weight yarn with a 3.0mm hook will give you a miniature version that is absolutely precious as a keychain or ornament.

The Mama Whale Pattern

Body

Start with your main color yarn.

Round 1: Make a magic ring, sc 6 into the ring. (6 sts)
Round 2: Inc in each st around. (12 sts)
Round 3: Sc 1, inc repeat around. (18 sts)
Round 4: Sc 2, inc repeat around. (24 sts)
Round 5: Sc 3, inc repeat around. (30 sts)
Round 6: Sc 4, inc repeat around. (36 sts)
Round 7: Sc 5, inc repeat around. (42 sts)
Round 8: Sc 6, inc repeat around. (48 sts)
Rounds 9 through 14: Sc around in each st. (48 sts)
Round 15: Sc 6, dec repeat around. (42 sts)
Round 16: Sc around. (42 sts)
Round 17: Sc 5, dec repeat around. (36 sts)
Round 18: Sc around. (36 sts)
Round 19: Sc 4, dec repeat around. (30 sts)
Round 20: Sc around. (30 sts)
Round 21: Sc 3, dec repeat around. (24 sts)

At this point, insert your safety eyes between rounds 10 and 11, approximately 8 to 10 stitches apart. Begin stuffing the body firmly. Continue adding stuffing as you close the head.

Round 22: Sc 2, dec repeat around. (18 sts)
Round 23: Sc 1, dec repeat around. (12 sts)
Round 24: Dec around. (6 sts)

Fasten off and close the remaining hole by weaving your yarn needle through the front loops of each remaining stitch, pulling tight. Weave in the end.

Belly Patch (Optional but Highly Recommended)

The belly patch gives the mama whale that classic two-tone look and adds so much character. Use white or cream yarn.

Chain 5.

Row 1: Starting in the second chain from hook, sc 4. Ch 1, turn. (4 sts)
Row 2: Inc, sc 2, inc. Ch 1, turn. (6 sts)
Row 3: Inc, sc 4, inc. Ch 1, turn. (8 sts)
Rows 4 through 8: Sc across. Ch 1, turn. (8 sts)
Row 9: Dec, sc 4, dec. Ch 1, turn. (6 sts)
Row 10: Dec, sc 2, dec. Ch 1, turn. (4 sts)
Row 11: Dec, dec. (2 sts)

Fasten off, leaving a long tail for sewing. Pin the belly patch to the underside of the body, centered, and sew around the edges using a whip stitch or mattress stitch. Weave in ends.

Tail Flukes

Make two identical pieces.

Round 1: MR, sc 6. (6 sts)
Round 2: Inc in each st. (12 sts)
Round 3: Sc 1, inc repeat around. (18 sts)
Rounds 4 and 5: Sc around. (18 sts)
Round 6: Sc 1, dec repeat around. (12 sts)

Fasten off piece one, leaving a short tail. Do not stuff. For piece two, fasten off leaving a longer tail for sewing.

Flatten both pieces and align them together. Sew the two pieces together along their open edges using the long tail from piece two, then sew the joined tail fluke to the back of the body, bending it slightly upward for that classic whale tail pose. The fluke should sit at a slight upward angle to mimic a whale surfacing.

Side Fins

Make two.

Round 1: MR, sc 5. (5 sts)
Round 2: Inc in each st. (10 sts)
Rounds 3 and 4: Sc around. (10 sts)
Round 5: Sc 3, dec twice. (8 sts)
Round 6: Sc 2, dec twice. (6 sts)

Fasten off, leaving a long tail. Do not stuff. Flatten and sew to the sides of the body, approximately at rounds 10 through 12, angled slightly downward.

Dorsal Fin (Optional)

Round 1: MR, sc 4. (4 sts)
Round 2: Inc, sc 2, inc. (6 sts)
Round 3: Inc, sc 4, inc. (8 sts)
Rounds 4 and 5: Sc around. (8 sts)

Fasten off, leaving a long tail. Flatten and sew to the top center of the body.

Finishing Touches

Use pink yarn or embroidery floss to make two small circular cheek blushes just below and slightly in front of the eyes. A simple chain stitch or satin stitch in a tight circle works beautifully. Optionally, use black embroidery floss to add a small curved smile below the eyes. A tiny ribbon bow tied on top near the dorsal fin area is the perfect final touch for a feminine look, or you can leave the whale clean and classic.

Baby Finishing Touches

Add blushing cheeks and a tiny smile just like mama. You can also add a miniature bow or leave the baby plain. Some crafters like to attach the baby to the mama with a short length of yarn looped through both bodies so they can be held together, which is a charming touch for display purposes.

Tips for a Perfect Finished Set

Consistent tension is the single biggest factor in how polished your finished whales will look. Try to keep your stitches even throughout, especially during the increase and decrease rounds, which are where tension inconsistencies tend to show up most obviously.

Stuff firmly but not so firmly that the body distorts. Amigurumi should feel full and squishy, like a good stress ball — firm enough to hold its shape, soft enough to squeeze with satisfaction. If the stuffing starts poking through small gaps between stitches, you either need to stuff more gently or switch to a slightly smaller hook.

When sewing pieces on, use the same yarn you crocheted with so the seams are invisible. Take your time with the tail fluke attachment in particular — the angle at which you attach it makes a huge difference in how lifelike and dynamic the finished whale looks.

If you are making these as a gift for a baby or young child, always use embroidered eyes rather than safety eyes, or make absolutely certain the safety eyes are locked in as far as they will go. Safety eyes are not suitable for children under three years of age even when properly installed, so embroider a simple eye using black yarn for any toys intended for very young children.

Gifting and Display Ideas

A mama and baby crochet whale set makes one of the most thoughtful handmade baby shower gifts you can give. Pair them with a small handwritten tag that says something like “you are loved more than all the oceans combined” and tuck them into a muslin gift bag for a presentation that will genuinely move people.

For nursery décor, consider displaying your whale set on a small wooden shelf alongside some faux succulents or fairy lights. The tactile softness of the crochet combined with an ocean-themed nursery creates such a cozy, dreamy atmosphere.

You can also photograph your finished whales and turn them into a digital product — many crafters sell their finished amigurumi or their patterns on Etsy, and mama and baby animal sets consistently perform well in that marketplace if you ever want to turn your love of crochet into a small creative business.

Final Thoughts

There are patterns you make and then there are patterns you return to again and again, adapting the colors, gifting them to everyone you love, making them for every baby shower and Christmas gift exchange on your calendar. This mama and baby crochet whale is firmly in the second category. Once you make your first set, you will understand exactly why.

The craftsmanship involved is genuinely satisfying — you are making something three-dimensional and charming from nothing but a ball of yarn and a small hook. Every round you complete brings a new part of the whale to life. And then at the end, when you set them side by side and see that enormous size difference between mama and baby, when you see those little embroidered smiles and those soft blushing cheeks, you will feel the particular pride that only handmade things can give you.

Happy crocheting, and may your yarn never tangle. 🐋
