So my 13 month old boy doesn't have a problem with putting food in his mouth for example I'll give him a tuna spread sandwhich he'll put a piece in his mouth suck the filling out then spit out the bread he just won't swallow it?? The same with any food he'll put it in his mouth then after a bit will just spit it out again. He'll only eat things that dissolve in his mouth like crisps, or stuff that is smooth like yogurt or fruit purée. What can I do about this?? I hate how he barely swallows anything!
