DD 5 only has her front teeth. She had to have 8 of them removed.
We brushed religiously every night and forgot the occasional morning in the mad rush for work.
I felt extremely guilty for ages and like a bad mother trying to think what else I could have done. Especially at the dental hospital having to get the lectures about sweets and fizzy juice, and the from the dentist when I explained she hadn't had fizzy juice in her life and could take or leave sweets. I bet everyone says that!
The one positive that came out of it though is that I went away and did some reasearch and I can completely see now how it happened. DD practically survived her first three years on an all fruit and veg diet, she wouldn't eat any form of meat or grains, except porridge occasionally on a winter morning. This led to constant snacking, "finger foods" that would sit on the coffee table for ages while she picked away. Pair that with being out of the house full time working and I can totally see where we went wrong now, obviously.
Raisins are 100 times worse than chocolate!
With DD2 we've stayed completely away from the whole baby led weaning phenomenon, she has proper meals at set times and a couple of snacks, but not allowed to pick as such like DD was. I think thats what the real problem was, her mouth was never getting the time needed to recover and get back to healthy PH levels.
