The pouch is based on mommy's size, not baby's size. My baby is 57cm based on 1 month checkup, now he's 2 months (so bigger than 57cm now) and still can fit in my size 3 pouch. In fact, like I said earlier, the pouch is too big for me and I'm letting it go.
I'll be getting a size 2, baby can still fit in.
