Thanks girls I am glad I'm not the only one that has a head banging / head hitting little one.

Salad - I read your post and starting thinking about all the things that DD eats that may have 160B in it. Mostly I cook all her food for her and try to stick to whole / natural foods as much as possible. BUT.... lately she has been having a lot of those rafferty's garden fruit bars and they have 160B in them! I couldn't believe it. DD has been a shocker lately and totally getting worse. Last night she hit herself in the head most of the evening, this morning the same thing again and then I realised that she's been having 1 (occassionally 2) of those bars almost every day lately!! They are so handy to just throw in the nappy bag when we go out or to add as an extra in her day care bag. She used to have one every now and again but they have become a regular lately, and so has the head banging and head hitting.....So now I'm thinking is this just a coincidence??? I'm certainly not taking any chances - from today she won't be having any more of those bars and I'll be checking the labels of everything else I give her to make sure it doesn't contain the same thing and see what happens.

Wow - I can't beleive that her behaviour may be influenced by this natural additive

I'll give it 4-5 days then report back!

Thanks so much everyone
