Dear Nathan,
You are obsessed with trains. Seriously obsessed. I've never seen a kid love something so completely. It's a single-minded obsession. You love the show Dinosaur Train - not because of the dinosaurs, but because of the train. You walk around the house saying choo-choo. It is the most bizarre and interesting thing.
To feed your obsession and make sure you would have a really good time one Saturday, we took you to the train museum. You didn't want to leave. They have a small train outside, which you had to hug. They also have a couple of real, full-sized train cars. You loved those the best.
There's a room with model trains that you can just watch go around and around an entire little town with all the details. Old-fashioned cars, little people going to church and sitting in restaurants, a circus, a drive-in movie theatre... just everything you can think of. You watched the trains go around and around for probably an hour without really looking up. I think you had a nice time.
You have continued to expand your vocabulary, sometimes saying words we wish you wouldn't have heard! But mostly, you are just saying all kinds of useful and interesting things. You love to laugh, and will take any opportunity to do so. Even if you have no idea why other people are laughing, you will join in. And it's the biggest, happiest laugh in the room.
Daddy is busy building you a bed for your birthday. A Big Boy Bed. I can't wait until you see it. You're going to love it.
I love you, sweetie.
All my love,
Mommy
