Personally, I've never liked the idea of feeding kittens human baby meat foods. I've seen owners at cat shows give it to their cats and tried it once with mine - they wouldn't touch the stuff
I find that a little KMR, canned kitten food and warm water mixed into a mush works a lot better to get them to eat. And when you start them on canned kitten food they rarely have problems with loose stools and can easily continue eating canned food and later the hard dry food.
I usually start with either the chicken or lamb kitten food, then add in beef a few weeks later.
