I get the negativity from my family as well my sister and brother in law are teachers I just let everyone know my decision not yours if I wanted your opinion I would ask for it it has gotten better over all I just ignore the comments others make because I know what Im doing is the best for my kids.
I have four kids with autism on different parts of the spectrum. there is family history my husband and I have autism. I wouldnt worry about it unless you see signs of it. if you do then take them in to get dx with it.
