Well, I finished the baby sweater. It looks pretty cute but I'm not entirely sure it will fit any baby. The neck isn't very big and it doesn't have too much give. The sleeves actually ended up being too long, but I cuffed them and think they would work fine this way. I asked a friend of mine with a 4 month old how big his head is and she said she wasn't sure, maybe 16" around or so. I'm not entirely sure if I'll give it to someone or not, but at least now I know I can knit a sweater.
