Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) is milder than autism. It's a label children are given when they don't meet all the criteria of autism, but have some developmental delays. Children with Pervasive Developmental Disorder Not Otherwise Specified will show different symptoms than others because every child's problem will be different. Children grow and develop at their own rate and children with PDD-NOS are no exception.

One of the symptoms a child might show is unusual behavior. Not every child is going to display this, some will. Let's look closer into this symptom.

1. Unusual behaviors in children with Pervasive Developmental Disorder Not Otherwise Specified can be a number of things. There are several behaviors that fall under this category. Your child may have repetitive actions. They want to do the same thing all the time, eat the same meal or just continue to do the same action over and over. This can include continually clapping their hands or twiddling their fingers.

2. Along the same lines, children with PDD-NOS like routine. They want to do the same thing at the same time everyday. They don't like when their schedule goes off track. If it happens, they could have an outburst or a temper tantrum that isn't a normal reaction to the situation. Children with PDD-NOS might set up their room in a certain way and if things are moved could get very angry.

3. Some children will become obsessed with a certain object or subject. If they like airplanes, they may learn everything they can. They will have pictures of them and stare at them in the sky. These obsessive behaviors usually only happen with one thing and the child won't care for much of anything else.

4. Learning a new skill is hard for children with PDD-NOS. Their developmental skills challenge them, but they also don't like change. This can include a number of things such as potty training, brushing their teeth or combing their hair. Because they are so into routine and doing the same thing, having to learn something new will change their lifestyle.

5. Some children with Pervasive Developmental Disorder Not Otherwise Specified have sensory issues. They may become attached to a certain cloth beyond the extent of just a blankie. This piece of clothing, or even a smell, could have an unusual calming effect on the child. They will carry this with them and never want to part with it. Many times, they will like something of the same texture and smell as well.

6. Sounds, however, have an opposite effect. Children with PDD-NOS don't like high-pitched sounds. When they hear some thing that is loud, they could have an outburst or a meltdown.

7. Your child may not want to cuddle. They may not want to be touched unless they are playing around. This is unusual in children and should be checked out if that is the case.

These behaviors can be caused by other problems in your child. If any of these behaviors are witnessed, speak to your doctor. Unusual behaviors are also just one symptom of PDD-NOS. There may be other symptoms your child will show if they have Pervasive Developmental Disorder Not Otherwise Specified.
