It's called milia and you will probably see it on and off for about the first 6 - 8 weeks, although from memory I think Pup had various spots for a bit longer than that.

DON'T squeeze them (no matter how tempting)! They go away within a matter of days of their own accord.

Occasionally babys can develop acne (I believe it is known as baby acne) and this can stay with the bub until they are about 2 when it also clears up of it's own accord. But I think it normally appears after the 3 month mark.

You're going to see HEAPS of dots, marks, pimples, rashes etc.... be comforted to know that they are all mostly normal and don't have any ill affect on bubby. But obviously go see your GP if anything looks REALLY out of place or doesn't clear up in a few days.
