Had my son at 25weeks 6days

My son is very small 1lbs 14oz and was taken to the NICU before I ever got to see him he's now 2.5 weeks old and I feel like I'm not even his mom I have "held" him twice both times was for 5 min very hard to feel a connection to him when all they let you do is look at him through a plastic box I spend all day at the hospital making medical decisions for him. He was born early because I had a weak cervix and went into labor. Any advice On how to feel more included in his care instead of just a helpless bystander ?
