Is she a drinker (pregnancy aside, obv!)?
If so, a quality bottle of wine, 30 y.o. port or a better version of her favourite tipple, maybe? It'll give her something to look forward to once she's had the baby.
I made my mum a 'foodie hamper' for mother's day. I went to my local deli and the Selfridges foodhall and bought load of yummy things (lobster pate, tarragon oil, handmade chocs, etc) and packaged it all up for her. Like an extravagant mini picnic.
