Night sleep

My son is 13 month old. He has this on-going “sudden screaming in the night” throughout his baby and now toddlerhood. It doesn’t happen everytime but it does make us feel exhausted when he wakes 2-3 times not wanting milk , and it’s not because of humid weather . Some might say that it’s “sleep regression” and I know not babies have this and not all babies are the same. Just wondering how many parents here are experiencing this? I heard that this sleep regression may go on till 2 years old.
