Ds3 is 6 (7 in February). Over the last few days he has had 3 large whiteheads on his face, each one appearing as the last disappeared.
He has always been more prone to spots/skin conditions etc than the other Dses, but this is more than he usually has.
Any ideas what it could be & what I should do? He has a good balanced diet, although I suppose there have been more sweet treats lately (still not sweets/chocolate every day but more than before, say 2-3 times per week). He hasn't seemed unwell either & we get plenty of fresh air every day.
