re: Parents with both boys and girls

4 yo Boy/Girl twins. Similar differences as yours (minus the forging - can barely write his own name), which I'm told is "normal" behavior. The girl is really easy (for now). The boy is testing my patience. The homework struggle is real, says its "boring." Talks back, defiant, wants to be outside only. Digs, climbs, etc - last week caught him jumping from powerwheels to clothes line, trying to hang on the line. O and he calls me out regularly - can't get much passed him and is extremely observant. So, not worried about him at all.
