Relax, hun, she's only 10 weeks old! If she sleeps better in the HAB and you are happy to use it, then do so. She gets a lot of comfort from being close to you, and who can blame her? Only a little while ago you held and carried her 24 hrs a day, now it's down to maybe 5! The fact she is so settled at night time should prove to you that you are not forming any 'bad habits', it's just when it's day time she wants your closeness and security.

Babies tend to draw confidence from the increased security when they are little and you will probably find as she gets older she will be more than happy to sleep in her bassinette.
