I know some of our Dec Babies have teeth already. Lexi's two bottom teeth broke through about a week ago, maybe a little over a week. Anyways, you can just now see them when she opens her mouth and smiles, but there's still not much to them. Being that Lexi is my first, how long does it take for them to come all the way in? I know they all develop at a different rate, but I'm curious as to how long I'm going to have to wait to see her chompers all the way! My mom said it could be up to two months and my MIL says a few more weeks. Very conflicting.
