Not sure if you can count a 15mo as weaning but it seems more appropriate here than under Food... !
DS would eat nothing but fruit and veg if I let him, but all he will eat in the way of carbs is toast and pasta. Sometimes will eat a tiny bit of potato/parsnip but very rarely. It's not inspiration I'm needing, as I know all about carbs and different things to try, but is it a problem if he has wheat at least twice a day, every day? He doesn't have a wheat allergy but could this bring one on?
