DS is now 8 months old and it seems that whenever he eats shop-bought bottled food he is sick. Not very sick, just a little normally 20 minutes or so after he's eaten. This applies to do different brands and different foods. He is ok with fruit, its just the main meals, lasagne etc etc. He is never sick when he eats food we've made for him (which is 95% of what he eats). I don't know why, what is it in bottled food that might cause him to sick? Is it something we should worry about? Anyone else had this?
