One of the coolest things about babies is the level of amazement and pleasure they get from things we take for granted.
Usually I dress my one-year-old in shirts with snaps on the bottom so they don't ride up and leave him cold. But recently I dressed him in a regular t-shirt and pants. He kept lifting his shirt up, pleased that his belly button was available for him to touch whenever he wanted.
Maybe there's something usually hidden (in your mind or metaphorically), but not that hard to access that will inspire your (or my) writing! Try something just a little bit different and you may be surprised what you discover!
