Those gourmet "add water soup mixes", the gourmet "add sour cream" dip mixes for her vegies, mail order fruit for yogurt/fruit/granola parfaits (had one at mcdonalds today).
I lived in my $10 walmart soft pants/top jammies. With a bra and undies I felt comfortable being seen in them by the female babysitters and female visitors. What a treat to lounge in comfortable jammies for three weeks straight. Buy them 1-2 sizes bigger than normal, to accommodate her swelly belly. The jammies I got came in xs to 3x.
Cliff bars (peanut butter or cherry) are a great bedside snack when I was alone and couldn't go down the stairs to get a snack.
If she likes mush, get her the Nichols Sparks book called The Wedding
$5 at Walmrt. Also good mush is the lifetime movie called "Baby for Sale". It's $4 at Walmart and at first I thought it would be sappy, but found it to be quite good, with a little Grisham type drama in it.
Give her a $10 ebay gift certificate that comes with a challenge of some sort (buy a toy from our childhood, buy a toy (body lotion, teddy, back scratcher...) to enjoy with her hubby when restrictions are lifted), buy her old junior high yearbook). I had 4 weeks of insomnia, so ebay was my best friend. Thanks to ebay I had Christmas shopping done at 3 weeks post-op.
Get her a prepaid calling card and tell her to call up an old childhood friend.
Buy her a three ring binder with divider/indexes so she can organize her recipe clippings.
Buy her a photo albumn and include copies of photos of your childhood.
If she sews, send her Christmas fabric swatches (the stores will give you their last year's samples) so she can make ornaments. She can glue kid fabric onto cardboard, slap on a photo and call it an ornament. I used dalmation fabric for the kiddo in love with puppies, rockets for the kiddo liking rockets... As long as their own photo is on it, the kids will adore them.
Does she quilt, croquet (sp), knit, draw, scrapbook?
Would she want Quicken software to organize her finances, prepare a will, start a budget?
Get her labels and file folders for all the medical bills she has to organize.
Get her mending supplies so she can darn socks and replace buttons.
Buy her the really nice $6 foam kits from Walmart. I just got them today for making photo christmas ornaments and picture frames. The kids are making them for their annual Christmas tree gifts for relatives.
Type up a list of your favorite books, movies, magazines, websites...
Remind her that she may have serious "brain fog" and not want to do anything at all for weeks. I'm an avid reader, quilter, busy person, and I wasn't up to concentrating on anything for two weeks. No tv, no books, no sewing... But I felt up to ebay and hystersister's web site.
I've been on bedrest for so much of the last six years, because of four different medical probelms that are now all fixed. The hysterectomy fixed the latest one. That's why I have so many ideas.
Many blessings to you for lifting her spirits, her worries and pain will be so much easier to deal with because she knows you truly care.
