Ugh, my back has been killing me lately. I haven't been to my chiropractor in over 2 years. I do have a massage gift certificate I need to use soon; hopefully that will help. I'm sure most of the problem is having two 1.5yr old babies to pick up all the time. I'm not sure how heavy they are, my scale isn't as accurate mettler balance scales, but I think they are both around 23.5 lbs. That's almost 50 lbs of toddler to carry around! It was much easier when they were newborns lol. Hubby also needs to go see the chiropractor, both of us need an adjustment really bad.
