[souffle]

He's lovely and looks to be coming on very well.
With the length of his coat he is likely a male as they tend to have that really long skirt around the back and females are more short and fluffy all over.
He should have two teeth on the bottom so you are right to have him checked. If one is missing the top tooth opposite it may overgrow.
If he's going to need frequent checking I'd progress the handling now to getting him happy running hand to hand. He will be skitty at first but will soon settle down for once he gets used to it. Make sure he can fee your hand around his body so he feels safe.
