What is with the vocalizing in her sleep. I could've swore today Ella was awake and crying for me to come. My husband went in to check her and she had her eyes closed fully sleeping. How am I to know if she needs me or not, I am nervous going in to check her as she may be sleeping and the noise of me coming in may wake her up. Somedays are more than others. Any tricks I should know about to tell if she is awake/sleep? Occasionally she does this at night as well, I usually wait 5-10minutes as I am not sure if she needs me or not, then I go in and her eyes are fully closed but then they pop open when she hears me. What gives?
