We use fairly good wraps I think. Talia has a mixture of ME, Tots, nature babies, wool, fleece. Elouise has lots of wool, fleece UD, ME, WN.
TBH I don't think it is the wraps, as we don't really get any leaks at night (but majorly boost ELouise's UDNN/WNNN) - although they are very wet by morning but can cope with that.
Elouise does drink a fair bit of milk and water, as she isn't eating much at the moment due to teething. Talia is Breastfed and does feed a lot but I think all babies do at this age?!
