pennie F has gone through stages of constant teeth grinding - they can last a few weeks and then he stops it again. I just ignore it cringing the whole time at the hideous noise and they stop doing it eventually. I find it comes back every now and again, particularly when teething.
On the sweets/chocolate front. I am somewhere inbetween I guess. I am not overly strict, he is allowed a small DF choc every now and again, or a biscuit or small bit of cake, and maybe a few times a week he will have an oaty biscuit or something like that, so a treat but not a terrible one. But most of the time dessert is fruit or a wotnodairy yoghurt and snacks are bread, rice cakes, organix snacks, fruit or breadsticks.
F has woken up full of snot this morning, and is also teething. Not sure if the snot is teething or cold, thinking its probably another cold. grrrrr
