Hello everyone, can you tell me when your kids want to sleep start rubbing their faces, we're not only rubbing our faces but also rubbing our ears, is this normal? I wouldn't say it's exactly rubbing, but it's touching the ears and my mother-in-law says something about his ears ??‍♀️I say he just wants to sleep! We'll have a professional examination in a week or two, calm me down.
