I have changed many diapers and that's because they were getting ruined due to breastfeeding. I am satisfied as I don't think I tightened the diaper too much. It has the line for the umbilical cord. They fit well on my baby who is chubby. BUT it's difficult for me to put it on her. Pulling from here, pulling from there until it goes up, it annoys me. They will probably be more convenient when the child stands on their own feet. Otherwise, okay, they could have been a little more economical.
