I am a fan of your work and have been looking at the Head Banging information, I am going to make sure we avoid 160b because I think that causes my 3 year old son to do head banging. My son has been eating custard, yoghurt (I have switched to the Jalna brand this week), and ice cream (home ice-cream treasure troves, lots of colours in it, so stopped them). He would generally have custard or yoghurt in the morning and either ice-cream, custard or yoghurt around 5pm.

I have taken 160b out of his diet, which I will do for a few weeks and then re-introduce it to see what happens. His head banging can be to put him to sleep and during the night and very early in the morning, approx 5am. He banged his head in his cot, which was probably around the time he started eating solids, custard and baby yoghurt.

Since avoiding annatto and artificial colours his head banging incidents have lessened. He has had one head banging incident this week around 5am in the morning on Thursday morning so he may have had something at child care that caused it. They do have Yoplait yoghurt on alternate days, so they would have had it on Wednesday morning. – Caryn, by email
