With both my boys, I find onesies the easiest way to go when they're tiny. Occasionally I'll throw some shorts or pants on with it but with how many diapers you change at this age it is just another thing to deal with so if we're at home, just a onesie usually rules.
It's not super warm here yet and I have this weird thing about newborns not being fully clothed! I guess because DD was born in January.
M has been wearing sleepers at night and he's swaddled. During the day it's onesies and pants or one piece suits with no feet. DH has mostly been dressing him as I can't get up too much.
It's been pretty rainy and cloudy around here since E was born. I also have almost NOTHING that fits him, everything is HUGE because his brothers went right to 3 month clothing.
All I have that fits him is about 6 sleepers and 1 outfit (onesie and pants). So he's been wearing sleepers day and night, and he wears his one outfit to church! LOL. I don't feel like buying anything new that he will only wear for a month or so, so we'll just have to make it on what we have!
