Non-parenting readers will have to bear with me while I complete my experiment ;)
Yesterday Izz spent most of the day in cloth, with no leakages! My mum picked me up late morning and we went to Boots to get some terries/pins/waterproof pants (until I can afford some nice wraps) and she showed me various folding methods (we're using the kite, as it seems give the best fit around her bum). This nappy was on for about 3 hours before I remembered to change her(!) and although it was wet, she'd not made a peep about it. The pee had soaked towards the outer of the nappy so wasn't rubbing wet nappy against her skin.
When we got home we used a Onelife nappy for onesize-fits-all nappy and she had this on for a couple of hours or so before bath and bed (still 'cheating' with a disposable overnight ;))
I've ordered a few Bumgenius (despite the leakage on day one, because I think I'd not adjusted it enough), a few FuzziBunz and some second hand Onelife nappies to go alongside the terries. If we find that one works better than the rest I'll probably sell or swap the others (and that's the other beauty of cloth: they retain their value REALLY well!) All in this has cost about £90, which is a lot up front but will save us money in the long run (especially versus the £150 estimate for the rest of the year in 'sposies.)
We've started the day in cloth today, and will aim to go all day (including a trip out to the park later). Today will be the deciding day. If we have no problems, then that's it... cloth all the way!
