My 4 year old has suddenly started wiping her mouth with her arm/sleeve constantly. It first appeared a week or so ago when she got a cold- she said her mouth felt wet, and we just assumed that she was stuffed up and was getting more drooly because of that (though she didn’t seem so). The cold has passed but she’s still constantly wiping her mouth. So far it hasn’t caused much damage to her lips/face but I’m wondering what might be going on. She’s been fine otherwise, no behavioral changes or stresses, everything is normal in other respects. I don’t want to overthink this but of course Dr Google goes to OCD, tics, Tourette’s, and other big things that I start wondering how seriously to take this.
