Help! My 6-month old doesn’t sleep through the night


My son is 6 months old and still doesn’t sleep through the night. I have tried everything but he still dream feeds at least 2 times a night. He is exclusively breast fed and barely takes a bottle. When he does, he only drinks 4oz out of bottles and nothing more. We started introducing foods when he was about 5 1/2 months hoping that he would be fuller and sleep through the night but still nothing. I haven’t had a full nights rest in 6 months and I need some help. Any suggestions are welcome.
