Yesterday I received this question:
There's two different ways I can do it. If it's anywhere from 1-3 kids that are coming with me (at the moment... but I think this number is about to rise), then I am comfortable going to the appointment on my own and cycling through the kids and taking care of everything. If I have 4 or more kids coming along, though, I will bring a grandparent or babysitter along to help.
For times I'm flying solo, I strongly suggest a stroller if there's more than one that requires a constant eye. Wednesday's ENT appointments, for example, went very smoothly because I had my mom with me and I had the triple stroller along. Emma was content to sit in the stroller until her turn (last). Brianna is independent and doesn't need wheels. The two boys also were in the stroller and we did the "baby swap" throughout the visit.
Having medical records at the touch of a button with a blog will be REALLY helpful because I won't have to say "I don't remember when his tubes were... June? July? Oh, right... it was almost August (Oops!)." Instead everyone's info "should" be readily accessible. I always bring a few books and if there's someone that I know is particularly irritable at doctor's visits then I try to find something special for them. For a while we had a Baby Einsteins "mp3 player" with a caterpillar handle. Emma was ONLY allowed to play with that toy during doctor's visits! My kids especially love photo albums with pictures of the family, so those stayed in my car for a while.
I also set up expectations for the kids during visits. Rather than going with their Whims during appointments, I also tell them "no, wait, sit nicely, etc" instead of arguing with the child. A second request (of the same) generally gets a response of "I already told you, now it just needs to be happen."
I teach the kids from their first visit that they don't play on the floor, climb on things, or mess with the doctor's equipment. I usually keep a 'restaurant' pack of crayons in my purse so they can draw on the paper covering the table.
The kids get 'used to' having to behave while we have a different one being seen. Yes, there are multiple disabled kids. No, I don't let them get away with anything that a typical kid wouldn't be allowed to do! :)
Hope that helps, tho that's a much less 'regimented ' approach than you may have been looking for. Blessings!
