I don't really know where to post this, so forgive me if it doesn't go here.

The past couple of weeks, I've been baby-sitting my 5yr and 2yr old cousins. My littlest cousin who will turn 2 next month, is not sleeping through the night. When she is here, I put on her music and lay her down with her sippy and walk out. She'll sleep for a couple of hours and wake up. She also does this at home with her parents. Sometimes she'll start screaming other times she fusses or starts to quietly cry until she gets your attention. I'll check her diaper, make sure the blanket isn't wrapped around around her, and re-do the proccess of turning on the music and giving her sippy. She either lays down and goes back to sleep or starts to cry again. I know it isn't really my place, but I was wondering if anyone had any tips to do before bed or what to do if she wakes up. I greatly appreciate it!
