Well if you have a baby mouse with no fur what you should feed it warm puppy or kitten milk (not cow milk, that can cause diarrhea) using a syringe. If you don't have a syring, you can use a piece of string until you can get one, just soak it in the milk until a drop forms at the end. If the baby mouse does not drink it take it to the closest RSPCA.
Do not take care of wild animals.
It depends on how old the mouse is. If it is a New-born then no the mom will leave the mouse.
That would be the feild mouse.
let the mother take care of her babies you just have to take care of the mother like feeding her making sure that she has plenty of water to drink and a clean environment.
When you think he/she is ready and could take care of itself
You don't touch them and just let the mother mouse handle it.

You can't treat small animals at home, you need to take your mouse to a small animal clinic for proper care and treatment, I hope your mouse feels better soon!
