Help ease my mind please

I have a 5 year old a 2 year old and a 2 month old. I’m pretty sure I have post partum anxiety. My 2 year old has been tip toe walking not all the time but I always catch him doing it. It stresses me out because I saw somewhere that toe walking could be a sign of autism. But literally everything is always linked to autism anytime i google anything that’s always what comes up. He talks and is very sweet and loving to all of us. I’m just worried and need some reassurance that he’s ok. Is this just a phase he never is walked when he learned to walk so I’m not sure why he’s doing it now. I’ll tell him to stop and he will but then he walks and does it again. He makes eye contact but not for super long idk if that’s bad or not or just his attention span isn’t wide. Please help me I’m losing my mind.
