Baby in nicu - small baby = easy labour, no night feeds/looking after baby, you can just rest and recover (not true by the way).
Child in hospital - sitting around all day playing on your phone and eating snacks from costa/marks and Spencer.
PS, just thought I would clarify I didn't think it would be easy before I experienced it, I just didn't think it would be as hard as it was. I normally do around 8-10,000 steps on hospital days with my 11 year old, probably much more when he was a toddler. And there was no sleeping all night when he was in the nicu either, I had to pump every 4 hours which took about an hour each time.
