Your autistic child is not following your instructions. You find it hard to calm him down and feed him. Frustrated by his activities? All you need is a calm and positive approach. No doubt handling an autistic child is going to be more difficult than other normal children, but you cannot blame your child. Only a few of these children are intentionally bad, and most of their difficult behaviour is a part of their disorder. Some tips will help you become a good parent to an autistic child.
Take time to know your child and understand what troubles him. Each of autistic children is different, and yours may be especially sensitive to something like harsh light. Understanding your child will improve the situation. Secondly, lower your expectations from the child. Do not expect him to sit still for complete dinner or do all his daily tasks on his own. The child can improve over time, but not without your guidance. Modify your home décor to be safe for the child, since he might do activities like climbing the fridge, or spinning in circles. Some autistic children want sensory inputs while some hate it. So depending on your child, you have to provide or remove the sources of sensory input whenever necessary.
