We have entered major teething mode now where something is always in their mouth.
They both have bottom teeth.
Andrew and Emilie are constantly climbing, kicking, and hitting each other and I never hear a peep. They trade bottles and steal toys and no crying. I read that they have a higher tolerance with their twin sibling because it has been like this since they were in the womb.
Emilie has her two teeth on the bottom in this picture.
