Before birthing, we had thread after thread of the "What on earth should I buy?!" sort. Now I'm curious - what did you use the most? What are you the happiest to have? What did you get and then never use?
Favorites for us:
Long sleeved onsies - I like putting a tshirt over them and then he's warm and happy.
receiving blankets - especially the Aiden and Anise (or whatever) ones! That was pretty much what he wore for the first months until it got chilly. I still use them for napping.
Soft Bums diapers - the only diapers we have now. Totally awesome. For nights we have microfiber inserts, for days he gets organic bamboo. He doesn't leak at night, even with just the one insert. (You have to figure it out and tug the crotch up, otherwise it gapes at the belly and you get peeeeeeeed on.
My high chair that sits on chairs. That thing is great! We've even taken it to a restaurant!
Our Sunshine Kids car seat. One carseat. Done.
We were given a co-sleeper, but the thing was too high for our bed and he was always attached to one of us. It got used a bit for putting him down for naps.. but that happened very rarely. Mostly it was used for storing blankets.
We have a stroller and we do use it.. but it already is too small. It's a Chico Keyfit system. He's six months old and the back is too narrow for his shoulders. Ridiculous.
