NicuProblem
I'm sorry you had such a difficult time around birth and in NICU, and I'm glad your daughter is safely home with you now - I hope she's doing well.
I work in P(aeds)ICU, not NICU, but we also often log visiting. How it tends to happen is as follows -
Someone mentions (for example, in handover) that the bedside nurse hasn't seen either of the parents today, or that mother seemed very quiet today, or whatever the particular (low level) issue is.
As it can be hard for an individual nurse to pick up a pattern (due to working shifts, also looking after other patients etc) a decision is made to monitor visiting over the next couple of weeks.
Meanwhile, either the bedside nurses or a more senior nurse will take the opportunity to catch up at some pint during the day and find out how the parents are, what their other responsibilities are, what support they have etc. These conversations simply happen in passing at the bedside, not as formal meetings or anything.
This means that over the next week or so there is a factual record of visiting and more detailed general information on the family circumstances. From this it is usually clear whether there is anything to be concerned about or not.
If there is no concern, as obviously in your case, you may never know the monitoring even happened. Concerns may arise regarding mother's mental health, family support, family interactions, child protection concerns etc etc - we see a huge range of different families from different backgrounds and need to know where to signpoint for help/support.
One other thing - had you requested your daughter's notes in our trust, you would obviously have received them, but an appointment would have been made for you to go through them with a member of staff who would have been able to explain things for you.
Hope this is useful.
