Russian Endearments?

[applementha]

 I'm writing the background for a character living in Russia in the 1840s, and at the moment I'm writing a scene between a mother and her daughter (who's five or six at this point). I was just wondering if there were any sort of endearments in Russian that a mother would say to her child; something along the lines of "my child," or "sweetheart" or something like that.

Thanks a bunch!!
