Depending on how much you want to spend what about a nice MUM pendant or something like that, she can wear it and think of her little one and her very thoughtful friend at the same time.

Otherwise i think the snacks is a good idea, what about a nice comfy summer dressing gown to wear in hosp, i was given one after DD and wore it for AGES, would have loved to cover my hideous BF nighties while in hosp with it.

Otherwise maybe just a small pack of things to use in hospital, relaxation cd, hand held massager, neck pillow etc etc?
