robin, he isnt a crier, he is more likely to just look away (or laugh). He rarely throws himself on the floor full on tantrum stylee. I could deal with that. He seems to be much more manipulitive.
Aero, he is very much like you say. Very determined, and will have go over and over and over. Very tiring.
It completely baffles me, he never stops all day really. I dont mean being 'naughty', I mean he's just in fifth gear all the time. I wish I had as much energy.
