Jaylen 3 года, аутизм 3 уровня, укусы: советы по воспитанию?

Hello everyone, it’s been a while being on here.. just wanted to update on here. Jaylen will be turning 3 tomorrow.. where has time went.. we are currently trying to convince again. Seems like my pcos has been bad now since having Jaylen if anyone has anything that would help or ideas.. please comment. Jaylen has recently been diagnosed with level 3 autism he is nonverbal, he is in play therapy which just ended today. He also does speech and I am and he is in therapy something called parents as teachers.. it is basically something that helps me with his stuff like his understanding.. we have been struggling with trying to get him to stop biting and pinching.. I just signed him up for like preschool. He is supposed to be also receiving aba but in my area they don’t have any openings until September.

I know kids around me in the past has bit but they eventually grew out of it and stopped doing it.. I just don’t want it to become a problem in school for him..
