Am afraid I don't know what to suggest, can only say how I felt when I brought our premature twins home, one after the other. With recovering from the c-section, expressing milk and travelling to/from the hospital each day, I was exhausted by the time they came home. I was also quite down because I felt I hadn't done a good enough job of keeping them in my tummy (sounds daft, but I felt it was my first job as mum, to look after them and keep them safe in my tummy).
I did appreciate a friend who came and cooked us dinner - I was ravenous all the time, but struggled to get out and shop, never mind cook when I got home. Cakes were good too.
On the one hand, I wanted to forget that they were premature, whereas on the other hand I was glad to hear of stories of premature babies who had gone on to be fine. Fortunately my MIL was born 2 months early, and she's a bright and lovely person.
In the beginning, going out with the twins was difficult. Not only were they constantly hungry (both had feeding difficulties so couldn't take in enough at one go), but when people saw them they would always comment on how small they were, which upset me. I would have loved to have a friend come and help me get them ready to take out, and then stay with me for the outing to help field off all the insensitive comments!
Agree with sweetie66, constant reassurance that you are doing things right is helpful. I also found it an anticlimax when they came home - definitely an odd time. They were already over a month old, but I felt I didn't yet know them, and since they came home well before their due date, I somehow found it hard to engage "mummy mode".
