Tell us about yourself!
Regarding your comment about never cutting the cuffs off. Im very glad you do not hem MY pants! You obviously don't alter your own pants. Nothing worse then putting a leg in, it catching on the under-turned fabric, and hearing that Rrrriiippppp of the new seam. I want my jeans finished properly, to be as if I bought them the correct length. Im in my 50's and I don't expect any growth spurs anytime soon.
Just wait till you lean in, and get bonked in the head! They ALL do it. Baby will probably end up bonking himself too. This is why baby toys are soft. They don't have muscle combination yet.
