I have been using the normal Lovies for my daughter for many months, I love them so much that I never looked back again. However recently I have seen advertisements of The Lovies Ultra and decided to try them. What a huge mistake. I have used about 10 nappies and my little girl has been pooping and peeing through the nappie. The straps scratch her hips and they are weak. After about an hour the nappy straps breaks of by itself. The sizing is 100% correct. I have never experienced this ever with the normal Lovies. I'm disappointed that I spend money on such a terrible product.
