The Alex Onsie is a little onesie - you may also call it a body suit, or a short sleeved and short legged babygrow.
It’s a gender neutral style for both baby boys and girls, and fits from premature sizes, to age 2-3.

This pattern is designed for the Preemie Crochet Challenge by Sunflower Cottage Crochet. As part of that event, this pattern will be free on the 16th, 17th and 18th of September, 2025, through the blog hop below.

About the pattern
This little onesie buttons down the front and across the nappy-diaper to make dressing and undressing a small baby as easy as possible.

Sizes
Finished measurement:

36 (41, 46, 51) 56, 61 cm

Tension/gauge

23 stitches and 24 rows in 10cm / 4 inches squared with 5mm hook.
Matching gauge is important to get the correct size. A free stitch tutorial for moss stitch is available here, https://www.ravelry.com/patterns/library/every-way-moss-s...
and the Afghan blocks can be used as a gauge swatch for this project, and later become a cup coaster or block in a blanket. Yarn requirements given are sufficient to make the onesie, and one 6 inch square block from the stitch tutorial.

Skill level
This is an intermediate level pattern, which might suit an adventurous beginner. It involves shaping, but only uses one simple stitch.
