yep v normal. Noah had this (he was born at 39 wks as well) and it got worse before it got better (one day we woke up and it was all over his body). Ppl recommended sorbolene but this didnt work for us, it made it worse. i was also using Gaia and this didnt help... now we use Dermaveen in his bath and a few drops of olive oil in his bath and this helped and it has completely gone now (but we still use Dermaveen and olive oil). I think it cleared up mainly by 2 weeks and completely by 3. Best of luck - there are so many things to think about arent there!!!
