I understand your husband may be upset, but that doesn't make it okay to talk to your son that way. Unfortunately, responding to fire with fire in the moment isn't going to get you anywhere. After you put your son to sleep at night, try to talk to your husband 1 on 1. Go in and try to remain cool calm and collected. Let him know you understand his frustrations (give examples how you may be frustrated too), but ask if he could please refrain from not yelling in anger. Express your concerns about your son and what you want to do as far as getting him seen by medical professionals. Ask what he thinks about what you say and what you guys should do. If you have any research to share offer that to him. Convey that the best way both of you will get through this is if you maintain a united front.
If your that concerned get a professional opinion… my son is the same age and says lil things but he is not autistic went to a specialist and all don’t be so quick to put babe in a category all kids move at they own pace
