@Melissa mostly jump and hand flapping when excited, spins when he is bored sometimes not all the time, he toe walks sometimes but I used to do that as well. He likes to hum or sing when he is bored or playing.
Yeah, those are normal in toddlers.
What behavior do you describe as stimming? Many toddler behaviours are similar to autistic behaviours, but they are a normal part of development in toddlers.
