Make sure you use a proper kitten milk replacement formula (not human baby formula) available at vets and good pet shops.
You can use an eye dropper BUT it would be preferable to ask your vet for a small plastic syringe and use that. Kitten will then be able to control the flow of milk by sucking it out of the syringe. And boy can they suck!
We started with a 1ml syringe and worked our way up over the next 2 weeks until we were able to swap over to a kitten bottle & teat.
