They do go through fads with their eating.
I found with the jar food or fresh they seemed to like one or the other ,depending what they were used to.My eldest had only homemade,so if I ever tried to give him a jar if we were out,he'd refuse.He 's actually be sick.
With my younger children I gave a mixture of both because I knew I'd need to use jars as we'd be camping when they were that age,and I had no way of making fresh.I did want them eating fresh though so I gave both.The texture is very different,jars have little texture.
I'd keep trying homemade,and your baby will get used to it.He's still just starting,but you may find him more willing to try all sorts once he can sit up and put things in his mouth himself.
