My dd is 4 and a few weeks ago I posted about shutting her finger in the car door. Well about a week later her finger was all better. No scarring or anything. It has been two weeks since then and dd is starting to suck her fingers again. I had noticed before that she had stopped even when she went to sleep. Now she's getting back into it. Should I try to continue to stop her since she had gone two weeks w/o doing it? Or should I allow her to start up again and wonder if she will ever stop?
