Lots of Congratulations to you and your family on the new arrival.
Hope she will recover soon and will be out of the hospital.
Forget about I-485 for few days (if you are waiting for your GC), it will not make any big difference. Enjoy your time with the new arrival, this is really precious time of one's life.
If you are waiting for the GC, may GOD bless you with your approval after this new addition in your life.
