Taking care of 2 week old kitten - help!

I volunteer at an animal shelter and recently they asked me to take in a 10 day old kitten to care for. This is the first time I've done this so I'm very nervous, I just want her to be happy and healthy. She's now 15 days old. I've been keeping her in my bathroom because it's the easiest room for me to heat and the rest of my apartment gets pretty cold. Because of that I can't really hear her cry so I just come in to feed her every 3 hours. (Was every 2 hours for the first 2 days.) I've never come in and had her crying for food though. 

I've been doing the same thing day and night, 3 hours apart feedings. I'm starting to get pretty tired (I'm also working and going to grad school) and was wondering if it would be okay to go to 4 hour feedings at night? If there is any chance in this harming her I don't want to risk it. I was going to move her to my bedroom but I really think its too cold for her, plus I have another cat and I don't want them to get in contact. 

Thank you for all your help!

My little foster baby Dove:

She's darling! I haven't cared for a kitten this young but I did help a friend whose rescue was even younger. I'm sure people with more experience will soon be here to give you lots of good advice but until then . . . .

Why worry about heating a whole room? Put her carrier in a larger cardboard box, with a heating pad. Have the pad so Dove can wiggle off to an unheated area if she feels too warm. Drape a towel over the box to keep the warmth in. This way, at night you could have the box right next to your bed.

Do you have a kitchen scale that measures in grams so you can check her weight every day at the same time, just to be sure she's gaining every day?

And my friend's rescue kitten (now a handsome big boy) liked having a clock tucked into his nest near his cuddle friend. We thought the ticking, like a cat's heart beat, would be reassuring, and he would squirm his way right up to the towel wrapped around it.

You're doing something really wonderful and loving. Good wishes and congratulations to you and to little Dove.

Thank you! The bedroom is really tough in general because its very hard for me to keep the other cat out of the room and the two cats have to be seperated.

She's definitely gaining weight

Catapault gave you excellent advices. Yes, you can take it easier at the night now.  When all cirisis are over, and she is not so tiny any longer.  After all, moms in the nature arent always giving them a tight schedule of feeding. They are often leaved several hours alone, as they are going out to find more food.  Take your sleep you do need.  Once up in the middle of night is more than enough now..

You are apparently doing just great!

Tx!

Good luck!

Weigh her each day at about the same time, and use scales that weigh to 1g - most kitchen scales that will do metric weights should do this.  If she is gaining 10g or more most days you can be sure that feeding less often at night isn't stopping her growing.  In a week or so you could try offering a little wet cat food - rub it round her mouth.  She will need some bottles for some time to come, but if she will start eating solids it will ease the burden on you.
