We have a small kitten that lost his momma and he is too young to eat regular food. So how do I get him the nutrition of his momma's milk?

I was told regular milk and you feed them through a eye dropper or medicine dropper.
How sad for the kitty to lose it's mom!

If you mean regular milk as in cow's milk, no... Cow's milk is very hard for cats to digest.

Prepare your supplies. Sterilize the kitten-sized baby bottles and nipples in a boiling water bath for about 5 minutes. Cool before using. Place a large towel, a rough-textured washcloth and a bowl of warm water on a table next to a comfortable chair.Fill bottle with desired amount of commercial kitten milk replacement such as KM R and a pinch of plain yogurt (for every feeding) which will help the kitty's digestion. There are several good milk replacers on the market, available in liquid or powder form. The ready-mix liquid is more convenient. Be sure the product is engineered for kittens and that it is fresh.
