My DS 2.8 seems to have just discovered that he can use his tongue to lick all around the outside of his lips and has been doing it repeatedly since Thursday so they are sore and red
Do I need to do anything? eg: put some cream on when he's asleep? Or do I just let it heal/toughen up by itself
I've tried discouraging him by telling him he'll make himself sore but it doesn't make much difference
Also could this lead to a cold sore developing? It looks like the corner of his mouth could be a bit cracked
Thanks if you can offer your experience of this!
