doesn't sound typical austism to me. but does sound like he is attention seeking.
what your saying about autistic behavior is not the case with all autistic children...there are many different behaviors that do not effect all kids the same way...there are also different severities for being on the ASD that range from very mild, to mild, to moderate to severe. She (steimy) really needs to get him evaluated to know for sure...he could have PDDNOS or aspergers even and very mild at that, my son is diagnosed PDD NOS mild to moderate and he loves to be hugged and he has no problem with being touched, he doesnt scream, he loves other children and loves to play with children...STEIMY if daycare has a concern you might want to take him to a developmental pediatrician or a pediatric neurologist to get him evaluated then you will know for sure, it could be some form of autism or maybe not, maybe something else but at least you will know for sure...do a search on PDD NOS see if any of that information can help you out in the mean time. good luck!
Sounds completely like normal 2 year old behavior. All my children also turned the t.v. off and on while we were watching (it's fun for them). Throwing toys, hitting, and pushing down the stairs is all normal behavior. 2-year-olds act on impulse and do not think about "what will happen if I do this". Autistic behavior is not wanting to be touched, screaming when someone touches them, rocking, playing alone, not wanting any other child interaction, not wanting adult interaction, being in their own little world. We have relatives with autism.
