My son who is a adult with autism, I notice his left upper are seems to be swollen or larger than his right upper arm, and a small bump ?

A Stitch In Time...: If he exhibits a lot of pain in that area or if he is reluctant to use that arm or if the skin feels warmer than the other arm or the swelling increases then have him examined by a doctor. Sounds like he bumped or otherwise injured that area or an infection is brewing so if you have any doubts about it, get him checked sooner than later. ...Read more

Autism is characterized by difficulty with interpersonal relationships, communication, using language and abstract concepts. Does your daughter speak, make eye contact, and engage with you and others? If so, she is not autistic - enjoy the flapping because there is nothing better than a happy and excited kid. ...Read more

How big of a red flag for autism is asymmetrical crawling. My baby is 8 months old and also will twirl her arm and wave left hand up and down on occas?

It's more of a red : flag that she needs a neurological exam by her pediatrician. Depending on prenatal, perinatal & post-natal history, there may have been changes in development of the white matter of her brain on the side opposite the extremities she disregards or doesn't use as well. If deep tendon reflexes & muscle tone/strength are asymmetrical, an MRI & pediatric neurology consult are warranted. ...Read more

4 yr. Old biting her arm and fingers at school when bored. Is it okay/normal? Teacher says when she keeps her busy she doesn't do it as much

4 yr. Old biting her arm and fingers at school when bored. Is it okay/normal? Teacher says when she keeps her busy she doesn't do it as much

Needs redirection: If your child is biting herself when bored or stressed, it is best to give her other activities to keep her busy. Gentle redirection can help, but don't make a big deal about it or it may become a power struggle. Sometimes, a substitute can be used- a stress ball or a "worry stone". If it continues to be a problem, check with a child therapist. ...Read more
