First clothes(which I have rolled up lovingly in the birth basket and go pull out and stare at in amazement every couple days) will be a diaper, soft onesie(I have never had onesies irratate baby), sleeper gown, socks, and a hat. I tend to be a bit Waldorfy in keeping babies warm! Sleeper gowns work wonderfully because I just lift for diaper changes, no buttons to fumble with(my fingers usually swell postpartum). It always amuses me how chickeny their legs look, no matter how big they are. I will say that sleeper gowns are terrible for carseats, you have to hitch them up to get to the buckle. :/
I Love the link to the muslin gowns!
