Hi Ladies, i need some advice.My DS almost 12 mths is still spilling his milk and also some of his solids up. I have taken notice today exactly how much and he brought up atleast 8 tablespoons of his of his milk and solids so far today since about 7am. I thought he would have grown out of it by this stage.I'm getting to the point where i think maybe he has something wrong with his tummy maybe? Is this normal? My 2 DD's never had any trouble with this sort of thing at such a late age
