question: I have a 2 year old and it looks like her 2nd molars are coming in.  I looked at her mouth this morning and she has 2 black (which I think is blood) spots where those teeth would come in.  One is more swollen then the other.  Is it normal for those to be blood pockets?  Or should we take her to a dentist today?  Please let me know. I'm a little worried
