Caleb and I were in the kitchen yesterday putting away groceries when we realized we hadn't seen or heard Jackson in several minutes. I called his name but he didn't come running like he usually does so I headed down the hall, to find I'd left the door to our bedroom and bathroom open. I ran into the room expecting toilet paper unrolled all over the floor or something equally horrifying. There was Jack sitting happily in the toilet and grinning ear to ear. I ran to get Caleb and we tried not to laugh (or upchuck) as we snapped exactly one photo before yanking him out, stripping him down, and scrubbing him with anti-bacterial soap.
PS- they make little seats that fit small behinds just for the "training years"
