How often do you visit?

I had to have an emergency heart surgery so I had a c-section at 28w. The other factor here is that we were brought to a hospital over the border from where we live so traveling is a little tougher. Now that I am home in my recovery we have been going every other day for a few hours and I just feel so guilty that it's not enough. I just got a call that he has been having too many breathing events where he is de-satting and he has a possible infection in his gut so they are putting him npo. I just don't know what to do and I feel like a shit mom for not being with him right now.
