I'm wondering what yours are. I'm thinking of taking one up for something to do on my days off. I have a 1-year-old and a p/t job...but I find myself getting bored and snacking.

Thinking of something my daughter and I can do together, perferably outside. Maybe gardening or something like that.

photography..........little swimming pool for your child to sit in............like you said, gardening.............walking............museums.. .......flea market shopping or just looking around...........take an adventure and do something in town you've done before..........go to the park

I've decided to take up bicycling. Just ordered my daughter a little helmet.

What better hobby than that for losing weight?

my mom and I used to shop together, lol

With a one year old and the comments about getting bored & snacking, I'm thinking you're looking for something you can do around the house to keep your hands busy, but that you can drop at a moments notice and not have to worry about something being left out, open, on, etc.
knitting, crocheting
cross-stitch
reading
crossword/sudoku
gardening, garden boxes, raised garden beds (square foot gardening)
scrapbooking (you must be accumulating photos)
beading?
stamping - small projects like greeting cards

just a few thoughts

My 10-month old and I walk around the mall a lot and sometimes I will take him to the park when it is nice out. I play softball at night though probably 4 times a week and everyone on the team helps me watch him. When I feel guilty about it, they say, "Afterall, it takes a village to raise a child; don't worry about it."

I crochet, knit, and I've started making my own yarns. I also do a lot of paper crafts and stuff like that.

I have been gardening like a mad woman... Digging, planting bulbs, flowers, roto-tilling, shoveling dirt, lifting edging blocks, trying to landscape the yard... It has been fantastic exercise (and a lot of work, too!) but there is nothing more satisfying than to see those little green plants sprout out of the ground and produce pretty flowers.
