A.S.
First i want to say good luck on baby number two that is very exciting.I dont have any very useful advice for you but i thought I could comfort you a little bit.I used to work at a daycare a while back and I remember several of the children doing the same thing it always bothered me to.I no that probably doesnt help much but I thought it might make you feel better knowing that other children are doing it.Also I asked about it then and some of the other teachers said it could be from teething.Hope this helps a little
