I found Charlie was the opposite, he wouldn't eat the pureed stuff. Would just spit it out, make chunks & he loved it. I wanted him to get used to both so he wasn't a "snob" to canned food when we went out. But he is LOL, he will eat somethings from a jar/can & I do use stuff when out. But I also bought him a pirate cooler bag so if it's arvo I can take his fruit & custard or yoghurt.
When I read up about the ingredients & found out that the first listed is what is mostly in the jar/can...I now find most is water & they really dont get any meat from any of them at all. Also many if you check have "apple juice" in the ingredients - that I'm not a fan of.
As Charlie eats a lot & chunks I don't do the ice cubes. I boil big hunks of vegies, & freeze in snap lock bags with other various hunks. Then just heat, mash with fork...often add rice, baby pasta, sometimes cheese, cottage cheese or what meat we are having.
