DS will be 8months next week and has been on so...

DS will be 8months next week and has been on solids for a while now. He has always eaten his veges and will eat anything we give him (fruit and vege). The last 3days he doesnt want anything to do with veges. He will eat his fruit ect but just no veges. I have tried giving him jared food I have tried mixing jared with homemade I have tried mixing some fruit with his vege to sweeten it but he doesnt want anything to do with it As soon as he tastes it he will turn his head and start kicking his legs are crying but as soon as i give him fruit hes a happy little chappy Any advice would be appreciated as i have no idea what to do (i have tried to introduce meat but his tummy gets upset it so will leave it for a bit)
