🪡 Step-by-Step Instructions

1. Make the Yoke (Top of Bodysuit)

We will work top-down in rows, then join later.

1. Foundation Chain:
   Ch 52 (newborn) / 56 (0–3 mo) / 60 (3–6 mo)

2. Row 1:
   Hdc in 3rd ch from hook and across. Turn.

3. Row 2 (Start raglan increases):
   Place markers at four raglan points:

   • After 8 sts (right front)

   • Next 10 sts (right sleeve)

   • Next 16 sts (back)

   • Next 10 sts (left sleeve)

   • Remaining 8 sts (left front)

4. Row 2 repeat:
   Hdc until first marker, inc, move marker, hdc to next marker, inc, etc. Continue across. Turn.

5. Rows 3–10:
   Continue hdc with inc at each raglan point.
   Yoke will widen into a rounded shape.

6. Check fit:
   When the width fits baby’s chest + 2 cm, stop increases.

2. Separate Sleeves and Body

1. Hdc to first marker.

2. Ch 4–6 (for underarm space).

3. Skip sleeve stitches, hdc to next marker.

4. Repeat for the second sleeve.

5. Continue around to join into one continuous body piece.

3. Crochet the Body

1. Body rows:
   Hdc in each stitch around. Work in the round or back and forth.

2. Shaping the waist (optional):

   • Row: [8 hdc, dec] repeat around for slight shaping

   • Next row normal hdc

3. Length:
   Work until the torso measures:

   • Newborn: 22–24 cm

   • 0–3 months: 25–27 cm

4. Shape the Leg Openings

1. Divide the bottom opening into two halves.

2. Work front section first:

   • Hdc rows across half the stitches for 4–6 rows.

   • Fasten off.

3. Work back section:

   • Same number of rows but add 2 extra rows for extra diaper space.

4. Crotch piece:

   • From the bottom of the front panel, ch 20–24

   • Sl st to the back panel

   • Work 3–5 rows of sc

   • Add buttonholes if desired

5. Ribbing (Optional but recommended)

Add ribbing around the leg openings, neckline, and sleeves.

Ribbing method:

• Attach yarn, ch 6

• Sc in each ch, sl st into bodysuit

• Repeat around using sc ribbing technique.

👶 6. Crochet the Sleeves

1. Reattach yarn at the sleeve underarm.

2. Sc or hdc around.

3. Decrease every 4th row for tapered fit.

4. Add ribbing at the wrist (optional).

5. Make sleeves as long as desired (short, long, or ¾ sleeves).

🔘 7. Add Buttons or Snaps

Recommended placements:

• At one shoulder

• At the crotch (for diaper changes)

Button row:

• Work 1 row sc

• Next row: sc, ch 2, skip 2 for buttonholes

✨ 8. Finishing

  • Pockets

  • Surface embroidery

  • Shell edging

🧸 Beginner Tips

• Always check gauge—baby clothes must fit safely.

• Avoid loose buttons that can detach.

• Use soft yarn to prevent irritation.

• Seamless bodysuits are more comfortable.
