So my toddler has this weird habit of picking up hair/string and putting it in his mouth. He doesn't eat it (that i can tell anyway). But it still bothers me. And no matter how many times my SO or I take the hair/string away from him and tell him no or to stop, he just does it again a couple minutes later. Same thing with his blankets, just sticks a corner in his mouth and chews or sucks on them. He eats a pretty balanced diet so I'm not entirely sure why he's doing these things. This all started in the last month. Any advice will be greatly appreciated.
