Any dentists around ? DD has weird teeth

[thingamajig]

She is 18months and has only got 8 teeth, which is fine. The bit I'm worried about is that her upper four teeth rest BETWEEN the front two and back two bottom teeth when her mouth is closed. I'm hoping this will get better when she grows more teeth, but its a bit weird. Is this normal? I had a friend whose (adult) teeth rested with the top ones inside the bottom ones and it caused her no end of trouble.

That does sound a bit odd - why don't you take her to the dentist. We've had our DCs at the dentists from 12 months onwards. But don't fret, teeth do move about a lot.
