I've only bought a few more cloth diapers. Kellyscloset.com was doing crazy things for Thanksgiving through today. I may even put in another order today, which will get me to a $10 credit for their site. I only cloth diapered my two part time, but with possibly three in diapers (maybe 4 if my 3 year old is still resiting potty training by then) I figured cloth would be a good investment and I don't have enough to cloth all of them full time.
Other than that, my friend who has a daughter the same age as my 2 year old has offered to give me all of her clothes. She's super thin though where my bio kid was a chunker, so if my girls are also chunkers, I don't know how much of her clothes with fit them. I did keep everything from my boys though (cribs, toys, port a cribs, swing, etc).
All I *should* need to buy are bottles, for when I go back to work and a five point booster seat. I still have my infant carseat and then one of the twins will get my oldest's convertible seat, which fits from 5lbs up.
I'm sure my mom will go crazy buying things once I tell her it's girls, so I still won't need to buy anything.
I will need to start looking for a nanny though, but I'll hold off another couple of months.
