my baby's so big!

Ty has been doing karate at school for a couple months now and they recently changed it to later in the day so I he basically just started the class when I get there to pick him up, so I get to watch! He is so cute! He is a really good listener and is probably the best in the class, I am not just saying that because he is mine, the teacher is constantly using him as an example of how good he listens and everything. I also like watching because it shows me how grown up he is. He can do everything by himself and he just turns around once or twice to waive and smile at me then turns back around to focus. I can’t explain it but it’s like he looks at me and says, “Hey mom, I am a big kid now playing with my friends, I love you and I’ll be right there in a minute but look how cool I am right now!” I don’t know how to explain it but he is just so cute! He's getting so big, he'll be 4 next month!
