My daughter is almost 10 months old.her 2 top teeth came in a month a part.it's been 1 1/2 month since the second, but they've barely grown. why?

Teeth: Baby teeth can come in slowly and often will appear very small for a long period of time. At 10 months of age it is likely that this is within the range of normal. If you have specific questions, make an appointment with your pediatrician to go over teeth eruption and how to care for your child's teeth now that they are coming through.

Genetics: The timing and speed of eruption is determined genetically, and varies slightly from person to person. There is nothing you can do to speed things up, so don't worry. I'm sure they will erupt completely before you know it.
