Hi M.,
My son also has Down syndrome. Email me at ____@____.com and we can talk if you want.
We did orthotics for Joe, too, but just foot ones. Your son probably doesn't like them because they feel different. Make sure they fit right and are not hurting him. His body is so used to one position that it can be very uncomfortable to put him in a new position until his body learns it. Sometimes we have to use our best judgement and follow our instincts. I wouldn't push him for the 2 hours or he'll really start to fight you on it and then you'll have more issues. Maybe start him with 15 minutes and work up from there. The thing you have to remember is these kids are "plodders". They WILL walk, read, etc., but everything is done in a slow progression. Have patience - you'll get there. Everything in it's own time.
As for your other kids sadness, really try not to dwell on what he isn't doing, but what he is. Reassure him that he will learn these things, it just takes him longer to learn. And make just as big a deal (even though inside you are flipping cartwheels!) when he makes each step along the way. Get your other kids involved in helping him to learn and celebrate each milestone with them.
When you are ready, I own a store with products for kids with special needs. I have a great product call Walking Wings that may be worth looking at.
Feel free to email me anytime. If you're not involved in a support group, I go to the Maple Grove one and have found invaluable information and support there! I'd love to invite you to join us at our next meeting. I'm almost positive that I've seen these orthotics on some other kids in our group. I can definitely put you in touch with those parents.
Keep your chin up!
