Someone (no clue, who) sent the following items:

Two 3-pack packages of Skip Hop 3 month side snap short-sleeve onesies- same pattern. Total of 6 onesies.
One package 5-pack of Carter's 3 month side snap (kimono) short-sleeve shirts.

I know the side snap shirts are handy when baby first comes home and has the umbilical cord. Shouldn't those shirts be NB size, not 3 months? Based on your experience with Carter's sizing, will the 3 months kimono shirts work?

If we exchanged one of the Skip Hop packages I would get the 6 months size, since we have the same pattern already in NB size.

TIA
