Doing your best
Again, having a child with a disability can be rough and is something that no parent is ready for. How can you prepare someone for something like that in the first place, there is no class. You just have to learn how to deal with it and roll with the punches.
Sure, it can be hard at times when they throw fits or have meltdowns in public like in this post. But you need to do your best to understand what’s happening and deal with the situation as calmly as you can. This father did just that and was complimented by a stranger who knew what he was dealing with.
