First tooth!

Less than 4.5 months old and she already got her first tooth! A couple of weeks ago I through the she was sick since she looked upset, was spitting up more, and had a low fever. I brought her to the pediatrician and they said they could feel the teeth under the gums. But they said it could be months before they come out. Well this weekend she was a bit fussier than normal. Cried when she saw some relatives and was harder to settle down. I checked this morning and sure enough I see a tiny tooth sticking out! I was really hoping not to have to deal with this for a long time. She can’t even hold the teethers in her hand for long yet. I bought a Munch Mitt but she hasn’t quite figured it out yet.
