My baby has stopped eating his solids??...?

My little boy is now just over 8 and a half months. He weighed 8lb 11oz at birth and now weighs 20lb 9oz. He started getting his bottom teeth around 4 weeks ago and now I can just see them poking through nicely when he smiles. He's always had a good appetite for his food since I started him on it around 6 months, but recently, especially the last week or so it's been a real struggle to get him to eat, he seems to just want bottles. I try to give him fruit and yogurt on a morning, which he's mostly eating, but then lunchtime or before bed when I try to give him his dinner or some porridge he flatly refuses, laying back in his high chair, wriggling down, screaming and turning his head away. I'm not sure why and I'm worried he's not getting what he needs. Is this normal when teeth start coming through? I'm thinking maybe they are really bothering as the last few days he's been completely soaking everything with dribble and that did wear off for a little while. I can't tell you how much food I've cooked up fresh for him thinking that it will help by making nice things for him to try but he just won't have it. Should i just keep offering it or just leave him with his bottles and maybe cold yogurts or fruit for a couple of days?? Many thanks.
