To have 1 child in MCN washing every day you would only need 24 nappies, but honestly, I dont wash every day, so my stash is much bigger than that.
Can I challenge that Ali I have 20 nappies and wash every second day, Matilda does sleep 12 hours straight at night though so in the same nappy. I use up to 5-6 nappies a day.

How many nappies does everyone else go through I change 3 hourly and 12 hours for night nappy (and of course an extra change when she poos).

Anyways... back to Marlene, I agree that he will be in nappies for maybe a year or so yet so definatly not to late to start. I would go for OSFA or maybe some large nappies too. I started with trting terry flats, did not suceed (I think due to my covers), I changed to AIO/AI2 and I love them and would never turn back. My staple nappies are Itti Bitti's and Baby Beehinds (mainly for night use).

It really isn't as daunting as it sounds .
