When my twins were admitted to the NICU in May 2015, I was an Air Traffic Controller in the Royal Air Force.
It felt to me like there was a societal expectation that now you were a dad you would immediately start parenting, but in reality, I was not. Nothing fundamentally changed for me while they were in the NICU. It felt like I was visiting a relative that was in hospital after work. It did not seem like it was my children, over which I had any control, authority, decision making, or power.
For me, NICU was very much about the mum and the children and anyone else is sort of surplus to requirement that staff would tolerate on occasion. If I went in to see the twins after work in the evening, it felt like I was an inconvenience. It was made quite clear to me that the twins needed rest, they did not need bothering by their dad of an evening.
It seemed like staff wanted me to essentially leave the twins alone, not to touch them, not to bother them. Sort of sit and observe them like they are an artefact in a museum – but please don’t try and interact with them. There were a couple of nurses that were quite proactive and told me “No, no, you need to be more involved”. However, I found I would go in on a Tuesday, one of those nurses would be on and encourage me to get them out to do something, but then I'd go back in on the Wednesday and be reprimanded for doing the same thing.
