Hi there, has he been eating with you at meal times or by himself? The playing, biting and spitting out is very normal - it's how they learn to eat. They need to be allowed to do this at mealtimes from the start. I have no idea what his history of solids is though.
I have no idea if the not swallowing is a medical thing or he just doesn't like it or isn't used to it.
Without knowing his solids history Some of this May or may not be relevant to you....with solids it's important they join you at mealtimes so they can copy you. They need to play with it, they need to get messy etc if he hasn't done this from the start he mày need to learn how to do this. Aargh have to go..
I waited until after his 6 month allergy testing to start solids with him, knowing already that he had food sensitivities. I started him on farex and purees. He was never really that keen, but I always stopped when he lost interest. At one point, he was eating 2 Tbsp soy yoghurt for breakfast, and 1/2 or a whole jar of fruit/veg puree for lunch and dinner. But then he started refusing to eat from a spoon around 11 months. It was a real struggle to get him to eat anything at all. I would give him objects to play with to distract him while I fed him, or had the TV on, just so I could get something into him.
I tried giving him finger foods, I ate with him at breakfast and lunch every day (we eat dinner late as DH gets home after 6pm most days), I'd even put a little bowl of soy yoghurt inside my bowl so it was like we were even eating out of the same bowl.
He surprises me sometimes. Like tonight, he swallowed a mouthful of chicken! And last week he ate raisins every day, but he won't touch them this week. I'm at a bit of a loss really.
