We discovered another way that Ethan is like his Daddy. Though he enjoys the playground he is quite careful and averse to climbing too high or things that seem 'dangerous'. Daddy remembers he was that way too when young and never did like to climb too high or swing too vigorously. So Ethan will wait till Daddy shows him how to do things in the playground before he attempts them, and sometimes need a bit of encouragement before undertaking the scarier things. Funny that Daddy loves fast motorbikes now...it must be a late developing thing that I somehow think Ethan will pick up too.
Ethan's motor-skills is rapidly improving now. Here he is in this video climbing the ladder with some help from Dad then enjoying the slides all by himself!
