I guess i blinked. I used to have this little guy I could hold with one hand and he fit perfectly on my chest. Now, that 'little guy' is about 35" tall, almost two and basically rules the house...and every playground we go to. No more does he need 'Da Da' to help him up a step and hold him while he heads down the slide....now it's run run run, climb climb climb, 'damn the big step and the fact that it's 10 feet off the ground, I'm doin it!' and zip, down the slide....time flies.
