I will probably say this every year until you are at least 20, so I'll just admit up front that it's totally cliche while still being totally true -- you have grown so much this year! I can't believe you are 3 already. I can understand most of what you say, even. And what you say is adorable. You have excellent manners, and you speak very sweetly, even though sometimes you can be a little devil. You say "please" and "thank you" all the time, and I do mean all the time.
The last time you and I were hanging out one-on-one, you filled every lull with a "thank you." I'm not sure what you were thanking me for, or if it was even me that you were thanking, but it's good to be appreciative! You are also very affectionate. You give superb hugs, and you tell people you love them frequently. I know that at three years old, you probably don't completely grasp what it means when someone says those words, but it always fills my heart with warmth when you say "I love you Aunt Egg," even if maybe it doesn't mean the same thing to you as it does to me. I know that as you continue to grow, you understand more and more just how much love is in your life. I think becoming a big brother has helped you with that, too.
You adore your new sister, and it's beautiful to see you with her. Even when your mama was pregnant, you would hug and kiss her belly, because you knew Sister was in there. Now that Sloane is out here in the world, you are just as sweet. You are gentle with her and give her lots of love and affection. She adores you, too. You are going to teach her so much.
While I gush about what a sweet boy you are, I can't just gloss over the fact that your nickname is Monster. You are an active and at times wild little boy, and you can test an adult's nerves like a champ. Your parents have been working on breaking your habits of biting and hitting, and it seems to be less of a problem these days. You're also so very good at apologizing, how can anyone stay angry? One time I was visiting your house and your mom and I were chatting, and you interrupted to say "Mom? Remember yesterday when I hit you? I'm sorry." Aww.
One more cute Jack story from the past year... A few months ago, you, your mom, and aunties were all hanging out together getting froyo at our usual place. When it was time to go, we were giving hugs, and I asked you if I could have a hug. You said no, and while that was a bummer, I don't believe in forcing anyone to give affection when they don't want to, so I accepted your decision and stood up to walk to my car. When you realized I really was going to go without giving you a hug, you yelled "HEY!" and came running to me with open arms. I'm so glad you wanted that hug after all, Jack. I love you.
