If you think of it from your DD's POV, up until very recently she's gone from being held, rocked, snuggled 24 hours a day to what is a dramatic cut to that time. It's only natural there'll be a transition period where she wants to be soothed the way she's used to.

As the others have said, this will change in time. You certainly are not creating any 'bad habits' for her, any more than carrying her in your womb for 9 months would have created a bad habit. Give her time to adjust to this new way of doing things.
