Signs. For some children, the signs are present in the beginning, while for others, the signs don’t begin to appear until the children get older. This can make it hard for parents to be able to tell that their child is autistic, especially in young children who may not be able to speak or walk.
Change. Katherine Alvarez told Babble that she didn’t find her son’s behavior concerning, but looking back she can see how he exhibited symptoms of autism early on. “We remember our son was growing and developing like a typical child. He was meeting and exceeding his milestones. Around 18 months things changed or I started to notice the changes,” said Alvarez.
No response. Then, Alvarez began to notice that her son started becoming less responsive and would hardly react to noises or people talking to him. Another thing she noticed, was how he would line up his toys in a particular order, which didn’t seem strange to her in the beginning.
