My wife just had a baby. He's two months old now. Things we appreciate other than the normal day to day stuff (diapers, wipes) include -
baby monitor,
diaper genie,
swaddles,
sleeper gowns - even for boys, gets you quick access to the diaper at night,
onses that have flaps over hands so they don't have to wear mittens
small fan - white noise
lanolin cream or some mixture with this stuff in it - for dry skin
nail files and trimmers - they get razor sharp nails that will cut their face
baby bjorn or equivalent - he loves it and I can get a lot of work done with two hands free,
stroller/car seat combo,
changing table - it's quick and easy at night,
burp cloths - they throw up all the time
one of those devices that cleans the bottle in the microwave otherwise sterilizing the bottles is time consuming and a pain in the butt.
Don't waste too much time or resources on:
a bassinet - he's already in his crib,
newborn clothes - get the next size bigger,
toys - he doesn't need much yet
I can't recommend the baby swings because he hates his. Every baby is different.
I recommend setting up an account on Amazon or Babies R Us to keep track of items you need and to share as possible baby shower presents.
