My daughter (now almost 18 months) has always been a bit of a late teether. She currently has her top two teeth, bottom four teeth and four molars.
However, according to the information I have read, she is very delayed in getting her upper two teeth (the ones next to her center teeth). This chart shows that they should come in between 9-13 months.

We are way past that and no sign of those teeth. I worry because I had issues with those teeth as a child (they were small and I had to have caps put on).
Anyone else deal with anything like this?
