Anyway a year later his behaviour at preschool has improved 100%. No longer any major issues. He's having Occupational Therapy for some sensory issues which is helping a lot.
Lately however I've noticed his lip licking again. I have been putting lip balm on at night and sometimes during the day which is keeping the skin reasonably ok but today after a day at preschool I picked him up and he has almost licked the area around his mouth raw.
Has anyone faced this problem - any tips? It seems to be a habit already but I'd really like to try and stop it before it gets too entrenched.
