Being a mom of a 5 year old it angers me that the other mother didnt acknowledge that your son was trying to look/play with the toy. Autism or not I have started at a very young age that if he did not want to share his toys he could not bring them out. Of course we have had melt downs when sharing actually begins but now he is totally on board. I just hate when we run into mothers or fathere that are totally blind to these things. No you shouldn't have to turn to shirts or jewelry to let everyone know, man kind should have compassion and I know that's a lot to ask. Who's to say that the family didnt have the money to buy the toy the other kid had and the other child was really trying his hardest to see and/or at least touch it. I know that this world my 5 year old is growing up in is something else but we have to teach our youth the right thing. Thanking for posting\sharing and sorry for going on and on but it's up to us as parents to open out eyes and help each other out.
