He may be tired, but those behavior problems are also part of the age. I call them the tyrannical 3's. I don't know where people got terrible 2's from because that is nothing compared to 3! They can do more things and are struggling to gain more independence, while still needing a lot of (unwanted) help. This ups their frustration level, but they still don't have the ability to handle all of those big emotions yet. And as you note, they are trying to transition to no naps. My 3rd son is almost 3 and full-on in this phase. I just posted yesterday about trying to maintain my sanity through this transition! It's not pretty, but it does pass. 4 is pretty terrific :) Hang in there, you aren't alone!
