The stroller will give the kid a security spot away from strangers and balloons. We can work on the balloon issues later as that is a bit hard to remember where they are located.
You can change the kid in the Baby Center, Nurses station and companion bathrooms if need be. The restaurants cannot legally take anything from a guest and nuke it for a guest or heat the item. They can provide you with ice for drinks and will make pureed foods for the kid. When you make the reservations for restaurants just tell them what needs the kid has.
You have a runner and those are fun until you chase them down. Make sure he has the number of your hotel in his clothing and your name. Calling you in Europe is not going to help the kid if he gets lost especially if they end up calling in our evenings which would wake up your family. There is 5 or 6 hours difference in time.
You should work iwth therapists to get the kid on pec boards and other communication devices and even sign language. I knew of a lady who raised her cousin's daughter who was born a vegetable. Last I heard the kid was using braces, sped around on her rump or the walker, and could sign her "uncle Sherman" around her little finger. With signing she was able to explain her needs and wants. You need to get over that communication thing.
SID is what I have and is common in spectrum, autistic, and neurovariants. The kid may freak out on you because that noise is not a beep beep but is more like
BEEP BEEP. The kid may not understand why he must do somethings, talk to bookworm about the psychology and thinking of neurovariants. "Go back" to a neurovariant may literally mean walking backwards and not to turn around and go back.
There are many tricks like ear muffs to lesson sounds or ear plugs. Tricks for waiting includes rewards for good behavior while at the store which you practice at or in line using ipods, radios, games, gameboy, toys, beads, strings with knots, and tiny tidbits of food as a reward.
The worst thing for me in line is my brain. I am sitting there worrying about am I getting my dinner and my brain needs to be running. I use a straw nowadays. I just twist that around my fingers to get pressure which is good for my senses, I love that pressure and the working of the straw wastes that built up energy. MY MOTOR IS RUNNING, HURRY UP. Autistic kids often have hyped up motors than need to be in constant motion even if it is just quietly setting with beads, demolishing a piece of cloth, or reading a book.
For Becky
I will let the others come buy and thanks for the information as we want to help you very much but our experience is that neurovariants vary so much that they are called neurovariants and many are on the spectrum.
No balloons, special diet, runner, still in diapers, and communication skills. That is easy, I have read about these and and the people here are knowledgeable on such matters.
