Children are so very physical by comparison to adults. Especially almost three year old boys I am finding. They are always doing, rarely sitting. Mostly running, rarely walking. And loud, really rather loud a lot of the time. And then sometimes they are so taken by their play that they 'work' silently for long stretches of time, digging, raking, filling the wheelbarrow, tipping it out and starting all over again, stopping only to inform you 'Mama, dirt in shoe. Yuck.'
