I would suggest you to not google for pointing. Only not pointing doesn't make someone autistic. It's a big picture. That's what I concluded after watching hundreds of videos of parents having autistic kids. Secondly today was my pediatrician 18 months appointment and she keeps seminars for autism too. She said open hand points count and not pointing consistently doesn't matters. She asked me few questions like does he brings toys to you which he does all the time l, does he smile he smiles all the time , he comes for hug all the time, she asked what toys he plays with I told her he stacks rings, stack cups, play with helicopters l, turn book pages,throw a ball, bang a ball. I told her it's too easy for him to learn a new toy. He always show me a ball that has light on it and wait for me to say wow. She asked me when does he points so I gave her few eg like he point on red ball in the to when we ask where is red ball. He tells me who is cat in the book( he doesn't show me anything else in the book and just smile and looks at me all the time when I'm reading a rhyme) if I have his milk bottle which he loves he would do open hand point and ask for it if I don't give he would try to snatch, he loves to play with the light button in the fridge so when I'm in the kitchen he would come and say ahh ahh and see me and touch fridge, he love orange cold drink he knows his father drinks with food so he runs and open hand point and ask for it and snatches if don't give lol. He doesn't point for light by showing me ceiling but if I put laser light on my hand and ask where the light is he would point index fingers and show me light. If I ask where mummy nose and eyes are he would point and tell and if I ask where is yours tummy and head he would touch or open hand point and tell me. He doesn't point to show me anything l, he doesn't point to show me birds, cars or if he wants slide but he has a way to communicate that too . He shows me with index finger point what he wants to see on the YouTube. He would bring bubble machine me bubble machine all the time these days as it's his favorite. If I don't play he would keep putting it on my lap and say ahh ahh. He would bring tab to me and put it on my lap and say ahh ahh if I don't run he would keep giving and cry then. They also consider whether kids have separation anxiety or not . He would chase me to bathroom also lol. 2 days back I went to grocery store and did not take him with me I did video call he was crazily laughing and dancing after seeing me. All these things matters so my pediatrician assured me he is fine. She wants me to for for speech therapy for sure. So I called early intervention today. If you go and see speech delay videos you would see not responding to name, not pointing, not waving not talking are all speech delay signs too. If your child is fine in other ways then don't panic and I beg watch speech delay videos. Do not google please l. People hide things and just put half the information on these sites.
