The joys of potty training!

So my Jackson is very independent and very strong willed. Awhile ago the boys were taking a bath and Jackson got out of the tub and said, " I need to go potty." So he sat on the toilet and went poop! He didn't have any interest for awhile after that but the last couple months I will randomly hear the toilet flush and he will come out of the bathroom without his clothes on. One time the boys were getting dressed for the day in my bathroom and Jackson said he was going to pee in the shower and he did. So lately he has been asking to wear "umerwear". He finally became very determined to wear big boy unders so I took him to the store and let him choose his own and he hasn't worn a diaper since! He does wear pullups most of the time mostly because he has a hard time going #2 on the toilet and I don't want accidents while I'm teaching preschool and I'm pregnant and tired! Despite the pullups he has been keeping them dry most days. We did have a few rough days/moments at the beginning. I think the funniest thing that happened was when Jackson rode his bike into the bathroom (he is CONSTANTLY on his bike). I stepped out, because like I said earlier he is very idependent, when I heard him calling me. "Mama! I spilled!" I go to check on him and he is sitting on the edge of the toilet because he won't let go of his bike to scoot back all the way and because of that he totally missed the toilet and got his bike!
