Normally Royal Canin Baby Cat.

I'm not sure why you don't like dry food, maybe because it is expensive.

then you need to buy chicken and meat. slide it into dice sizes. half boil it with empty water. make it something like half cook. and feed your cat. (to be specific, this kind of home made recipes won't give enough nutrition). Why dry food? because it is made with complete nutrition and vitamins, beside it is convenient. Still feed fresh food like chicken meat and cow meat is good, if you have the time and money to buy fresh meat.

Milk? any pet or kitten milk at the petshop will be OK.

If you want a simple life, growing healthy kitten, just buy Royal Canin Baby Cat, it is design for 1 month old kitten.
