Various, I have been in hospital with my own children at times, I have been in nicu with two babies as a nanny, many years apart- that was hospitals where the parents could go home to sleep if they wanted to, as long as they left someone else with the baby, and I spent months visiting hospital regularly this year, with my friend who had a baby in nicu, and her husband was in hospital too, with an unrelated condition, and so it was just her all alone day and night. They allowed me in the nicu because she was all alone, normally it is just parents. It wasn't just me, we had a relay team of friends coming in to sit with her for half a day, bringing clean clothes, wash bag, snacks, etc. All babs recoverd and went home and all doing fine, except possibly the last one I mentioned who may have cp, or might just be a late developer, time will tell
