anniversary cards are tough at times like these. Maybe get a blank one and write a short and simple message in it.
love the canal walk idea....if you only take a walk you could bring a blanket and champagne or wine bottle and just sit and talk and have a glass of wine or two (not more or you'll get mushy or pushy)
If you look at the past, review the good times & laughs. When she told you she was pregnant, how each child was, their first days of school, teh first fist fight, or boyfriend/girlfriend problem...what you wish for them.
This is "future" talk without being R talk...and it's past talk without dragging in the crap.
the birthday ideas are great. They are sort of acts of service (massage, factial, etc) so I don't think they're too mushy but they are useful and relaxing and will generate positive feelings in her.
GOOD LUCK
