Girls... Basically, I'm in the bathroom and hear my husband calling again and again, hurry up! He says so. Well, I got out of the bath, ran to the room (it's good that we live separately ?), and it turns out the daughter is laughing in her voice ? This is our first time, just for the record. The 16th will be 3 months old. When did you hear the first laugh of your child?))) Something again can't make me laugh ????
