I'm not sure if he is tired or cranky or what, but he is having a REALLY rough day. He's screaming and throwing a tantrum at the littlest thing. It is incredible hard for me to not run downstairs and get in M's way. It sounds like M is going to have a rough day.
He drops something, he throws a fit. If Little N colors outside the lines onto his side of the page, he throws a fit. It's like he completely forgot how to cope with little things without throwing a fit.
It's not like Big N to act out so much.
