Hi Beckibee

Yes this is quite normal. Your baby is used to the noisy hospital. You could try leaving a radio playing at night or have a ticking clock close to her also put the top you have been wearing in your babies crib/cot she will be able to smell you.

I would expect for your baby to find her own routine in a few days. She has to learn the differance between day and night.
I think there are some articles here on BB about this.

If I can be of any further help just let me know
