Skyeblue-Gosh these little babies are worrisome arent they? Sounds like it is fairly normal as bubs is getting bigger and is now probably having a sleep and awake cycle. That's great that you have the doppler to check the heartbeat, but I would definantly still give the hospital a call and see what they say. It's always reassuring to get monitored.

I hope your little girl starts moving a lot more soon. Take care
