Thanks for all the quick replies.
I think most of the pockets I've got coming come with microfibre inserts but by the sounds of them they probably won't be much good some possibly have bamboo and there are some AIOs so not sure whats in them. I haven't ordered any inserts yet so what would be a good mixture to try out? P'tit Dessous, Easy Peasy hemp, thirsties prefolds, the ebay ones, any others? Also I had a quick google for the P'tit Dessous but could only find them out of stock could anyone recommend a website please?
He doesn't wee too much and goes through 3 -4 disposables a day (generally changed for poop not wetness) and his nappy doesn't seem too full in the morning. He is quite an active sleeper so I think its probably best to prep for him sleeping on his tummy and that's a good idea about bulking the front out a bit. Our DD could wee from England but sometimes his nappies barely feel wet at all. He drinks quite a lot but his doctor said something about his poop taking a lot of the moisture....
Do all inserts / boosters need to be washed 8-10 times to start absorbing properly and do they have to be full washes or would quick washes do the job?
Thanks for all the advice I just can't wait for everything to come so I can start putting it to good use..
