Read this website. It's all about hand-feeding kittens. Halfway down the page there is this:
"MATERIALS YOU WILL NEED
You will need to be sure you have the right supplies on hand. You;ll need to have (or make) an incubator (or a nesting box); and you will also need a heating pad; room thermometer; sterile cotton balls and gauze; an accurate gram scale; nurser kits with bottles, nipples, and cleaning brush; Pedialyte unflavored liquid; high quality Kitten Milk Replacer formula (while the powder is more economical, we only use and recommend the liquid form in the cans); and, in case you need to do tube feeding, you will need several syringes (usually 3cc, 5cc, 12cc and 20cc), and your tube feeder, which can be purchased through veterinary clinics or supply houses. Many breeders recommend the butterfly needle infusion sets as the tube is very pliable, and soft. The 0.6mm (outer) diameter tube is most popular, and the rubber catheters you will need can be found at most major drugstores. You will need a #5 French catheter for kittens up to 2 weeks old, and you can use a #8 French for older kittens."
Get that baby warm first!!!!
