You go back to the reflection of a baby. He looks cute, maybe a year old, holding a large plastic rattle. There is a stuffed lion next to him, and he is wearing a diaper with Lion King characters. Being a baby for a little while could be fun. Anyway, you are just going to try it for a few minutes. You step through the mirror...
And are suddenly flat on your back, looking up at the barred sides of a huge crib. You wave pudgy arms and gurgle, then stick a fist in your mouth. After a minute, you pull the drool-covered fist out and squirm around so that you can pull yourself up using the crib bars. The rattle slips out and hits the floor with a dull thud. You have a sudden urge to cry, but stifle it. What is wrong with you? You can't remember how to talk, and though you are able to stand easily enough with the support of the bars, trying to walk in the crib is too much. This baby's body must include the baby's mind! Or at least, have the restrictions of an infant. You remember being older, you just don't have any of the skills that went with being older.
That includes potty training. You wet your diaper as you stand there, and wrinkle your nose at the urine smell. At least that's all you have let loose. A lady comes in to check on you - your mother? She is a giantess to you, cooing and making silly sounds. Is she talking to you? You don't even understand most of the words. She discovers your wet diaper and picks you up and carries you over to the changing table. Some baby wipes, a dash of powder, and a clean diaper later, and you are back in your crib. You gurgle and coo, which makes the lady smile and tickle your belly. You giggle, and wave your arms and legs, not really thinking of anything.
When she leaves, your mind focuses again. You are starting to think like a baby! If you stay here much longer, you'll forget overthinking and just be the baby! Where is the mirror that got you here? There is nothing on the ceiling, and the sides of the crib are plain. You saw a mirror on the wall over the changing table, but you can't see that from the crib. Then something clocks in your scattered memories. The rattle! It had a small mirror on one side! But it is on the floor! You pull yourself back up and try to peer through the bars. The floor looks clean. Your lion is still in the crib. Mommy must have put the rattle away. Or maybe taken it to wash it. No! Not your mommy! The baby's mommy! But - you are the baby.
You get distracted by your lion, and plop down to hug it and then hit the sides of the crib with it. What were you looking for? Oh! The rattle! It is very hard to focus. How can you get the rattle back?
