This is all something for them to pay very close attention to for sure. If the poor kid is diagnosed their life will change dramatically whether they want it to or not.Up front I want to say I'm not diagnosing Jackson but I just watched a youtube video of a mother who spoke about what she saw as the top 5 things her 3-year old daughter did from an early age before doctor's confirmed she was on the spectrum (note, her older sister who is 5 is also on the spectrum).
1. The little girl did not give her mother eye contact even when the mom was right in front of her face. She would always avert her eyes to include when she was nursing. The older daughter would give her parents eye contact but not as much as other children.
2. Starting at the age of 18 months, the little girl would not respond to her name. No matter how many times they called her by name, she would not respond. The way the teachers working with her got by that was to stop calling her by her name and then she would slowly start to respond. The older sister did the same thing. Now the older sister will respond because she expects her parents to give her some information or something fun.
3. Lack of communication. The little girl knows 10 words but she won't use them. She continues to babble and combine sounds but no real words. She communicates with her parents non-verbally.
4. Self stimulation. The little girl will self stimulate by twirling around like a ballerina, watching things spin, or moving her head back and forth. It makes her very happy.
5. She doesn't play with toys normally. She loves to line up her My Little Pony toys from largest to smallest or put her other toys in order. If she has a box that is hollow she will try to find a small box to fit into it.
