4 months and 1 week or 18 weeks nearly 19 weeks when did they start to sleep through the night 😫

My little boy is just over four months old he is nearly 19 weeks, can I ask when your babies started to sleep through the night he wakes up every four hours and in between that he is usually stirring, you go down around seven and wakes up at 11 then sometimes again at 2 and then sometimes it again at 4. I was hoping it was going to easier by now but the routine doesn't seem to be changing any advice would be greatly welcomed. Before the clock wake is the hardest one as I don't really think he needs to be awake but he just wakes up and starts whinging
