I think it's better to be over packed then under packed ..
I must've done my baby's hospital bag about 4 or 5 times and re folded and reorganized her clothes and other stuff about a dozen..
I packed
pacifier
one pijama onesie
two regular onesies
two pants
two pairs of socks
3 pairs of mittens
3 caps
2 bows
2 receiving blankets
1 thick blanket
1 thin blanket
and the sanitary kit
Depending on where you deliver they provide some of that for you I delivered at Methodist and I way over packed and only used onesies, socks, mitts, hats, and clothes for pics and a thick blanket they had provided reviving blankets, burp cloths, pacifier, the suction bulb. Had j known I would have packed less bc after o felt silly having so much for he baby. Didn't even need!
