Whoa! Hold on there!
give them puppy milk!
You can't give rodents puppy milk; it'll kill them. Get powered
kitten milk replacer with twice the water recommended.
Also, don't use an eye dropper; use a medical syringe. It gives you more control quile feeding and revents the little ones from invahating food. If they do inhale their milk (you can let if they do this if milk runs from their noses and they start coughing), turn them upsidedown and rub (not pat) their backs.
What are you keeping them in? Make sure it's closed, because once they open their eyes, they'll climp right out. Also, make sure they are away from drafts and vents, as well as direct sunlight.
Once they start crawling around, put in some rat chow from the pet show, as well as crush, unsalted peanuts, and allow them to nipple. Once they are eating it regularly, wean them off milk.
I've raised squirrels all my life, as well as a few mice, so ask if you have any more questions!
