L.O.
oh my Gosh, my son went through the same thing, except he only did it with me...anyone else could change his diaper with no problem...he just finally quit one day, but he was about 15 months when he did that stuff! i would literally have to wrestle him to change his diaper, and then one day he just quit...it was just a phase, he's 2 now, and we are working on the potty, but he's not really feeling that too much, but Good luck, it will just magically go away one day!
