My son is 10 weeks old and i am convinced he is teething. The only thing that makes him stop crying is rubbing an icecube on his gums. Is it okay that I'm doing this? I read somewhere that little babies can't have water... I am waiting for DH to get me an icecube tray to freeze BM into cubes(we have an ice maker in our freezer) Should I continue to ice with water until I have a tray?
