This is an interesting shift so far but you still have that elementary school question. Boy or girl that doesn't sound fun. Another change is in order.
"The 7 year old boy stands in his bedroom."
Here you go time to go for something even more extreme.
"The 1 year old boy stands in his room."
Your legs now have a rubbery quality that you weren't ready for and you fall into your padded butt. You feel like crying but the action is stopped by the pacifier you discover to be in your mouth. Taking stock of your body you find yourself to be wearing a Mickey Mouse onesie covering the previously noted diaper.
The room now is perfectly suited to an infant; with a crib, changing table, and plenty of stuffed animals and other baby toys. If going from a grown woman to a baby boy doesn't spark something you'll never be a writer. You crawl over to the crib and slide the phone under the mattress for safekeeping. With that done and no school in sight you decide to try out some of those toys.
