Ds is only 4 months but I can recommend going to the Chiro, he helped with the reflux he was having and through a process of elimination we worked out he had a problem with lactose. He reacted to my breast milk even when I cut out all dairy but he improved once on lactose free formula. He is finally putting on weight after losing a lot and getting our pead very worried. He is still medicated for reflux but it's much better.

Apparently it's rare but he was born with a low grade fever so it may be the reason he couldn't cope with it. It's more common to react to milk protein.

I have been told he will outgrow it by the time he is walking rather than 12 months. His sister were around 18 months when they walked do I am hoping he will be earlier.
