That is such a good question. My baby will be 4 months on 7th Jan, and she has been teething for over two weeks (Yes, teething!!). She's been constantly dribbling and shoving anything she can get her little hands on into her mouth. I tried the gel teething toys, but she can't seem to get a good grip on them. I try to hold it for her, but she doesn't like that either. She's so little, I think they're too big to go in her mouth at this stage.
