Is 4.5 months too young to nap train? DD used to be SUV a great sleeper. I mean, would sleep throug anything and go to sleep anywhere. Now she fights it so hard except at bedtime. As soon a she is tired she starts screaming and insists on being held/rocked to sleep and cannot be put down.

Do I just let her cry? I don't know if I can do that! I try and catch her sleepy before she realizes it. I also have to cover both of us in A&A blanket so she can't see anything because she's so distracted. Ughhh!
