Baby on Board: Careful

The trek up the stairs was surprisingly strenuous for Mikey, and he nearly fell backwards once or twice. *Geez, you'd think I'd be used to the weight by now, but it throws off my balance every time* Mikey thought to himself. Wait, what threw off his balance? Once he reached the top of the stair, Mikey realized his back was killing him. "I need to go lie down..." he said, not noticing that he was walking into the master bedroom as opposed to his own, or that he had aged three years since putting on the shirt.
