Yeah, but she'll only put herself back to sleep in the way that she knows how - in your DD's case, crying . My DS did the same thing for a long time, he has always fought sleep in some way. I personally didn't feel comfortable with letting him cry on his own. I know he was still crying, but at least he could feel comforted while doing it. I figure when I'm upset, it's nice to have someone caring with me - I'll still be upset, but won't be alone. So I have always held my DS while he's going to sleep, crying or not.

And cc in any form is not recommended for babies under 6 months, as the damage it can cause is now known. Not trying to upset you, just letting you know
