I suspect my 3year old (4yrs next month) has a lactose intolerance. she was complaining of her stomach hurting several times a day every day, it got to a point in January where she would just lay down and clutch her stomach until. it would usually last until age did a poo. Her pops smell atrocious and acidic and are not diarhoea but are quite 'loose'. We stopped giving her dairy for a few weeks and she quickly stopped complaining if stomach pains and her growth has thrived. She has always been a small child in height and especially weight and has trouble putting weight on. In the 6 weeks she has been off dairy she has put on a good amount of weight and looks a healthy weight for the first time in ages. however we have been trying different milk and milk alternatives to find one she likes (wasn't a fan of almond milk) and she has gradually started to her used to the taste of soy milk. However the last few days she has had a soy milk popper for breakfast and she has complained her stomach hurts again . So now I am at a loss because if its lactose intolerance shouldn't soy milk be fine?
I think she is going through a major growth spurt at the moment as the last few days she is cranky, complains that everything from her legs to arms to head hurts and is a bottomless pit when it comes to food.
So now I am confused if the stomach pains are related to the growth spurt or to the soy milk or if we are just completely on the wrong track. We don't face a regular Dr here yet and most of the medical clinic ones are useless.
