DS2 got his first tooth at 13 months (5 appeared all at once), a 6th one followed a couple of months later....and nothing since.
Should I be worried or have others got children who are 'late' teethers? DS1 had all his teeth by the time he was 2 so probably had at about 13-14 at this age.
(Tbh, it fits perfectly with the rest of his development...late crawler, late walker, late talker - my mum often jokes that if I hadn't had an elective c-section, he would never have come out )
