Phew! I'm not alone! My sweet 2 year old that never fought our bedtime routine etc....where did he go? Now it's big boy 3 year old who is all about "I do it myself!". Mine is a screamer/screecher (when he's happy or mad)....sometimes it feels as though my eardrums are going to explode. No amount of timeouts, quiet reasoning, positive or negative reinforcement has quelled this. But, I keep chanting to myself "this too shall pass".
