Hello, she is 6 weeks old. Her belly button hasn't fully healed — there's a small hole. We put brilliant green (zelyonka) on it twice a day. I cut a hole in the diaper for the belly button, but my daughter kicks her legs so much that she still fiddles with it. I'm worried; the pediatrician said everything looks fine internally and there's no inflammation.
