I've been using these for less than a week. We just started potty training our 2 yr old. She was in huggies pull ups but we switched just to try something different. Well were going to be switching back. She started to complain that her pee pee hurt and she wouldn't even let me touch her. She looks red and irritated and keeps holding herself. So we went back to pull ups and she's been fine. Not sure if it's the blue cooling strip that has irritated her or what. We've always used pampers and have loved them. Not this time.
