Some thoughts from an LP adult perspective . . .
It is okay if your child does not have access to a disabled placard. There are many LP adults whose parents did not have a disabled placard to use when we were young. In fact, there are some LP adults who don’t have a placard because they don’t want to live a life with special adaptations, which is awesome. Any kid has to learn early to be aware of our surroundings, not to walk away from our parents’ car when in the parking lot, hold someone’s hand, and always wait before crossing. Having a disabled placard should not be a right that’s misused. And an infant with dwarfism who cannot walk yet does not need a disabled placard.
