A friend of mine has a child with asd, he’s 3 years old and very well behaved on his own but violent to other children. I want to meet up for play dates but he keeps hitting my DS who is 11 months old. I don’t want to subject my DS to the constant hitting or throwing of toys at his head/face but I also don’t want to isolate my friend. Any ideas on how we can handle this? I am so stuck.
