Is anyone else greedy with their baby?

My daughter is 3 1/2 weeks old and I hate letting anyone else besides her Daddy hold her....my mom calls me greedy and stingy...but I just want her all to myself. Is that wrong of me? She has Cystic Fibrosis which after I founf that out at 12 days old just made all this worse of course. I just want every minute I can have with her. When I am apart from her too long like in the shower or something I get a mini anxiety attack. She sleeps in her own crib at night but I am constantly making sure she is ok. I wasn't like this with my son...who my sister had for us and I love deeply and just as much as his sister.....perhaps it is because she came from my body though that I am feeling this way? I was a great Mom to our son....but I did share him a little...this time it is almost too much though. I feel though that I cannot change how I feel and that others will have to just hold her for little bits of time and be satisfied. Also some people smoke and that bothers me when they want to touch.
