My 2 month old daughter has thumb sucked occasionally since she was born ( and possibly b4 that! As she appeared 2 b doing it @ the 20 week scan!!!!)
I thought it was just when she was hungry but the other day she was on her thumb 5 minutes after polishing off a formula feed, so there's no way she could hav still been hungry.
We r trying dummies ( even though I hate the damn things!) but unless u physically hold it in it comes out and she goes straight back on2 her thumb.
I have heard that it can push the front teeth out of line and having to have numerous braces myslef as a child/teen, I don't want her to go through all that.
Any advice????
