@NurseRosie I am sorry you have had such an upsetting time with your baby and I hope for a swift recovery. Sorry also you have had so many responses that have not taken into account an OP who is in hospital with a small baby: a truly upsetting experience. That is the problem with AIBU, rather than with MN as a whole, I think.
It is a while since my DS was a baby, but the nurses reacted with glee when they discovered I was a b/f ing Mum, and scurried to ensure that I was fed. If we arrived just after a meal time they would retrieve cold chips, carrots the size and texture of mangol worzels and proudly present them to me, urging me to eat.
My DS has had 15 operations, and it is good to get off the ward and seek food - but it is so expensive - and you don't always want to leave them. A sleeping baby in a cot, a dash out can sometimes be managed. But I never wanted to leave 5 year old, or 7 year old, or 9 year old DS in post-op pain, alone on the ward for very long. Hospitals are massive places - getting along the corridors, in and out of lifts etc, to a food outlet , then there is a queue....and your child is in pain.....and it takes a long time.
It's hard. Many aspects of having a child in hospital are hard. The noise, the lack of sleep,.... the worry, the need to be calm and re-assuring for your child, whist you are clenched with upset and worry inside.
Having something simple taken care of is a godsend.
