You are 49 months old today. Happy New Year!
Where you also excel continues to be in physical endeavors. Santa granted your request of a hula hoop and skates for Christmas.
My biggest piece of advice for you, even as you grow up and become an adult, is to keep to a consistent night-time routine. Every night for as long as I can remember, I have taken a bath, put on some lotion and read for a bit in bed. With few exceptions, this practice has allowed me to unwind and prepare my body and brain for rest.
When you have children of your own, you will need this advice, both to keep up with them and to help them learn to wind down. Trust me. You prove it to me every night.
