I like how the hood and hat remove the need to worry about the heads, and I could concentrate on the pose, trying to get the weight of the child in his arms. The proportions of children is always a test, as they can get a bit ETish if you aren't careful. And they always seem lost in bulky clothes such as winter coats. In fact it seems to me that all the work in this sketch is being done by the Father's front arm, that is the bit that describes and makes sense of everything else.
