My son also finds Heinz a bit hard to chew. I try morinaga as well, he usually drop most of it after holding for a while. I let him try Organix Rice cake. This is the best so far. Even though it is round shape, I can see he hold it really well. Sometimes he will use both hands and I can see him chew bit of it. I highly recommend it , you can buy it in Park'n Shop (Only superstore or bigger branch which stock more western food.)
