I used these nappies with my first child and liked them and am now using them on my second child. I find them great for containing breastfed poo and aren't as bulky as other nappies but still good and absorbent. The poppers make fitting the nappy to your baby easy and, unlike other 'onesize' nappies I have used, these really do fit small babies as well as they fit bigger babies. Well worth the investment as they will truly last birth to potty.
These were the very first re-usables we bought for my first baby 3 years ago and they are still going strong. They are very absorbent, and unlike some one-sizes they do fit from a tiny baby to a rather large toddler (my 3 year old still wears one at night) Great value product, the only downer is that they arent 'funky' like some others but you can always top they off with a quirky wrap
