Already so attached to our baby

My mom came to spend the night tonight for our first night home to watch the baby and let us rest. He's our rainbow baby after miscarrying in November. My mom is an amazing mom and had four of us so I know she can handle the job but I've found myself so nervous and I'm only down the hall in the bedroom! Lol we went to bed at 8:30. I've FaceTimed my mom from our bed and checked on him twice! Lol it's amazing how attached you get before your baby is even outside of the womb! Please tell me I'm not crazy for worrying so much!!
