much better confo pic - - looks like you have a nice baby there!
Your hands are much better in the second undersaddle pic!
For numbers (they always give us flimsy things!) we put a pin in our jacket midway between the soulder blades (insert it so that you can't see the clasp; the clasp is on the inside of the coat), put the metal part of the number through, expand the metal part below the pin so that it can't get through it again, then pin the number with a horsey pin.
:)keep up the good work!
ETA: try hair nets (i know, gross, but they flat out work!)
