This newborn sweater is built top-down in one piece, so there is almost no sewing at the end. I designed it with a gender-neutral colorway in mind, since it works as an everyday layering piece rather than an occasion outfit. If you have made a hat or a pair of booties before, this is a reasonable first garment. The raglan shaping is simple math, not tricky stitch work, and I will walk through every increase round.
Materials
- 2 skeins DK weight (#3) yarn, about 350 yards, cotton or acrylic blend
- 4mm (G-6) hook
- 4 stitch markers, yarn needle, 3 buttons
- Sizes: newborn to 3 months
- Finished chest: 18 inches, length: 9 inches
Gauge
14 stitches and 10 rows over 4 inches in hdc. If your swatch runs smaller, go up a hook size. If it runs larger, go down one. Fit matters more here than on an accessory, so do not skip this step even if the sweater seems small enough to eyeball.
Abbreviations and pattern notes
This pattern uses ch (chain), hdc (half double crochet), sc (single crochet), and inc (2 hdc in one stitch). Where you see a number in brackets, that refers to the 3-6 month size; the number outside brackets is newborn. Every row begins with a turning chain of 2, which counts as the first stitch.
Pattern instructions
Body and yoke
Chain 34 [38]. Work the raglan yoke top-down in hdc, placing 4 increase points, one at each raglan seam, every other round. By round 8, my stitch count reaches 66 [74] stitches, and I set aside the 2 sleeve sections to work the body flat from there.
Sleeves
Rejoin yarn at each underarm and work the sleeve in the round, decreasing 1 stitch every 4th round until you reach 20 stitches at the cuff. This keeps the sleeve from ballooning at the wrist, which is the most common fit complaint on newborn garment patterns.
Bands and ribbing
Work the neckline, cuffs, and hem in back-loop-only single crochet for 3 rounds. This back-loop technique creates a stretchy ribbed look without switching to a different stitch. Space 3 buttonholes along the left front band, evenly spaced starting 1 inch from the neckline.
Finishing and seaming
Sew the small gap at each underarm closed with a mattress stitch, then weave in every end along the inside seam so nothing scratches. Block the sweater lightly if using a natural fiber yarn, since blocking evens out the raglan increases. Sew on the 3 buttons to match the buttonhole spacing from the band step.
Frequently asked questions
How long does it take to crochet a baby sweater?
Most crocheters finish this raglan sweater in 6 to 8 hours of active work, spread over 3 to 4 evenings. The yoke increases go quickly, but seaming and button placement add another 30 minutes at the end.
What hook size for a baby sweater?
This pattern uses a 4mm hook, but gauge determines fit more than hook size alone does. Swatch first. If your 14-stitch swatch measures wider than 4 inches, size down a hook; if it measures narrower, size up.
How much yarn do I need for a baby sweater?
This newborn to 3-month size uses about 350 yards of DK weight yarn, roughly 2 standard skeins. Buy a 3rd skein if you plan to add stripes or a contrast button band.
