I have yet to find a wrap that will fit around lil mans legs! He's got no meat on his bones! Just bones! EVERYTHING I've tried is leaking right away. There is to much room around his leg from the covers not fitting right. Will wool help this? Do I need a cover with them, or is it cloth, the wool in place of the cover? I've checked diaperswappers abd theres so many that im now confused!
