Liam,
Right after bedtime is probably not the moment to write this to you. Bedtime can kind of be a war of attrition with you these days. Tonight, it took so much effort to get you to put on your pajama shirt. So much effort. You can be a super stubborn kid and there are contexts when that is amazing. It is going to serve you so well if you learn how to channel it. But the pajama shirt tonight...dude, I was already exhausted before that mess.
But here is the positive spin I'm going to put on that: I think the reason that you fight going to bed is because you enjoy being awake so much. You enjoy playing and being read to and eating and doing everything else a little boy your age does. You are so radiantly full of life. Even though this force of nature that you are tries to barrel through your mom and I sometimes, I am kind of in awe of it. You seem to go after each day like it's an adventure to be had. Witnessing that is a blessing to your nearly 30 years older dad.
