Hollo,
As the others have said... All babies are different, heck my 2 are prrof of it!
There is no such thing as a bad habit or making a rod for your back etc with a new born baby!

Imagine if you had lived in the comfort of a tummy where all your needs were met & in 6-8 or even more weeks someone expected you to be comfortable, fitting in, safely, securely etc... If you had no voice to talk with what would you do???

Please darl, dont be so hard on yourself...

Some evenings I soak in the bath with my baby for 20+ mins til she was settled.... We'd then cuddle wrapped in a towel slowly get her dressed & then let her feed/suckle & transfer her to bed, she felt safe & secure next to my naked body floating in the bath, it was beautiful & relaxing for both of us!

You do whatever you need to get some rest, sleep with her next tio you dduring the day, it is surprising how an afternoon nap can make things seem brighter!!!
