Meep! My answer would be a lot... I was going to use cloth nappies but Anna is so tiny that none of the ones I bought fit her - Newborn clothes still swamp her and the reusable nappies I have are intended for baby from 10lbs up so Anna has a way to go before she'll be in them!
I've had Anna for 17 days now and we've gone through 4 packs of disposable nappies (now on the 5th) (24 in a pack)... I'm pants at math but I'm sure someone more intellegent can work out how many nappies a week that is! lol
ummm... Crikey, that's about 48 nappies a week isn't it?!?? So about 6 or 7 a day. I don't know if that's normal; I started breastfeeding properly when Anna was 2 days old, and the following day she was doing yellow poops - she hasn't stopped since! lol I take it as a good sign that my breastmilk is getting through her okay, though
[Edit: We use Tesco's own 'ultra soft nappies' - They're cheaper than huggies or pampers or other named brands but just as good!]
