My four month old DS2 has shown all the classic signs of teething which, combined with a stuffed up nose, has made for a few interesting nights.
Today we saw a white spot on his upper rear gums - it seems as if a molar is breaking through.
Researching various forums tells me that's unusual, but possible. If your babies were the same, did they cut all their molars first or did the teeth come in the usual order, eventually?
DS1 got all his teeth as per 'normal' schedule...
