I came to this site when I had the same problem. I got really nervous when a bunch of Gus' teeth fell out. He was 5 months old. I couldn't see teeth coming in underneath and got upset but people here told me it was normal. I felt so much better. The teeth came in so fast, it was amazing. Now he has such nice teeth except for one last sharp baby that is firmly still in place. It will probably have to be pulled.
