Have started using the medium size cotton bottoms and wraps after dd grew out of small ones. Am i being really stupid but the actual nappies don't seem any bigger than the small ones. Thet are marginally wider but not longer which means they have big gap at each end of liner if u see what i mean. Have been usin ggirl fold. tried folding mall ones long ways but is too long! Any ideas!... btw DD is fairly heavy wetter. pees for england!
