this won't be long as my head still hurts from sinus pain.
we haven't gone totally dairy free as in we still allow some foods with milk protein in them. but we;ve cut out milk, yoghurt and cheese and any other big dairy items.
the changes we've noticed are:
* less aggressive
*getting dressed was a major issue, he would always kick, scream, punch etc. now he even gets his clothes (unless he gets distracted with toys on the way)
*more responsive to discipline. still has his moments but no is no and he doesn't kick the doors down (very rarely anyway)
* don't know if it's just a fluke but he is eating better at night time meals
so they are great changes. he is still full on, like most boys, but the aggression is less.
