By the time you go through the whole stuff-gathering kid-loading getting-into-the-car ritual you've forgotten where you're supposed to be going.
When shopping for kids clothes, you don't just look at how cute an outfit is, but if it's 100% cotton, has tags, that can be easily removed, is hard to take off, can fit over AFO's and feeding tubes, is trach friendly, and covers an ostomy bag well.
You know the "good vein", and what color vials they will need for the blood draw.
When walking down the hall of you local children's hospital, everyone from doctors to the cleaning staff, addresses you and your child by name.
You don't go into a restaurant with your child without checking to see if it has the one item he'll eat. And you might even want to take a look at it to make sure it'll be acceptable to him.
