Are you concerned about it, do you think it's worth seeing a paed? Sounds like he definitely has an aversion to swallowing larger pieces of food and I would be curious to find a if there is anything more to it. I am not sure what is considered normal but I don't really chop up anything for my DD unless I want to cool it down faster. For example, she had a banana for breakfast which I gave to her whole and a normal size spinach and feta muffin for morning tea
