At that age, both wet and dry food, then. Even if they don't eat much of the dry food, that gives them something to crunch down on for the teeth that they're cutting. Most of the dry kitten foods can be moistened with a little water, too, if soft food suits them better. My kittens always waded in to the dish with both front feet.
They're young enough that socialization will do wonders for them. Get as many different types of people in to see them as you can. Men, women, kids. Have them hold and pet and play with the kittens, maybe offer a little bit of baby food on the tips of their fingers if the kittens are shy.
This should be only a few minutes at first. Let the kitten lead the way. If they struggle to get down, hold them a few seconds more and then let them loose. This lets them know that you aren't trying to hurt them, but you ARE in control.
The more you hold and cuddle and play with them, the tighter they will bond to you. It's the kittens that are left alone who tend to be stand-offish as adults. (It used to be that 'experts' would tell you that kittens should not be played with, because somehow that was thought to harm them.) They do need naps, just like all babies, so it doesn't need to be someone holding them all the time.
I always started my Siamese kittens on this kind of socialization as newborns, even. It was only a few seconds at a time at first, stroking them with one finger and talking to them quietly, but it set the pattern for kitten-human interaction. One of my favorite memories is DH cuddling a newborn kitten and murmuring "Welcome to the world, little one."
Then back in the nest-box before their mother had a hissy fit. (Believe me, Siamese can throw major-league hissies.) Usually she wasn't worried anyway.
