Autism questions

Macey • I'm 18yrs old second pregnancy first child a boy. Who should be arriving around December 4th 2015, his name is Patrick James Noonan and daddy and I are still together.
So I live at home with my family because I'm only 17 and my 6 year old brother has autism. He isbalaays pounding and kicking the ground and yelling and I was curious if this will make it hard for my son to sleep or of he will get used to it. Please let me know anything that helps :)
