Additional Note: After putting the 3 month old size on my 3 month old, the asymmetrical neck seems wide on that size baby. For the smallest sizes, I think the V neck will fit better. Or another solution might be to make a size smaller sweater, since it’s so roomy to begin with. Another option would be to make a less drapey sweater by sticking with the needle size recommended on the ball band.

Also note, the sleeves needed to be rolled up.
