heres my 2 cence, but for those of you have spent lots of $ already its probably not to helpful.
I have cloth diapered my 2 yr old since birth using motherease one size, and i can count on one hand the number of leaks we have had, their airflow covers are awesome, seem loose but rarely get a leak.
i am also now using same dipes (used for 2 yrs and still great) on my newborn, yes they are bulky, as have to fold over for a tiny baby but they work awesome, and it only took me a day to get over how huge his bum looked after the teeny sposies i had on till his cord fell off. I now love his big cloth diapered bum.
I also dry pail and wash every 2.5 days (only wash then as would run out of dipes if not), and i wash on cold (max water level) with a tiny bit of tide free, then a hot wash (low water level), then one final (loads of water) cold wash. It took me ages to find my routine but now dont have any stains, and ds never gets a rash from too much detergent build up.
in regards as to them getting wet straight away, thats why you have the cover. I change often and always after a poo but you cant possibly change after every pee, as my little guy would be changed after 5 mins, as always pees pretty much as soon as ive changed him. But another thing i learned from these boards is to buy some fleece and cut into panty liner types shapes (no need for sewing) and use inside the diaper, that way the fleece wicks the moisture away from the babies bottom and keeps him dry and comfortable, and its also easier to flick the poop of the liner and helps to keep stains to a minimum.
Hope this all helps, as this is all the info i wish someone had told me at the beginning, hang in there its worth it in the end, and i find no more work at all once get into the swing of things.
