I've been thinking (yes, I know - that's dangerous!
), and for our LO due in Feb I was thinking about using muslin squares as pre-folds under a close fitting wrap (have two first size ME rikki's and a small lovely fleecey lovebums) as I figure they'll be slim fitting and more than enough to cope with those 'ickle newborn wees, plus as LO won't be wriggling to much they'll stay in place fine. Once LO's out of the small wraps, I was going to switch to a two parter - have fluffles and medium ME airflow wraps from DS and got on with this fine - as I find this great for those runny poos!
This should last until 8 months or so if DS is anything to go by, just in time for pockets to give a good fit (and weaning to help with consistency at the other end!
Sound like a plan?
