Advice for the future - please help

Hi, 

I was talking to my husband last night who has learning difficulties about our eldest child who has ASD and learning difficulties. My husband was telling me about his childhood/teenhood and that he was taken advantage of and he is scared for our eldest child and worries how to keep him safe and protected as well as our other nt children. He wants to keep parental controls regardless of age of our children and wants to ban social media. Can I ask how have you managed things with ASD and nt children? Do you allow social media for all or limit it?
