I'm going to join in too! I have a history of significant weight gain in each of my last two pregnancies (50-60lbs), and usually about 15lbs in the first trimester. I don't get nauseas, I get hungry! But rather than trying to diet, I'm focusing on making healthier food choices, and exercising! I'm a runner, but it's never felt good during pregnancy to me, so I've been going for brisk walks, and mixing in a little jogging here and there to keep my heart rate up. I'd also like to break out the prenatal yoga dvds, and I also have this hilarious bouncing excercise ball video for preggos, I can't remember the name. I'll start that in my 2nd trimester.
I keep track the old fashioned way- with smileyface stickers on my calendar. I aim for 5/week. Last week I got to 4. This week I have "planned" 6 days, so life can get in the way once!
Keep up the good work girls!
