Fellow mummas... please explain this one to me?

My little monster had been sleeping great the last month or so... sleeping right through or only getting up to have his dummy put back in or nappy changed... but recently I feel like I'm back at the new born stage only the little monster thinks it's play time at 1am he can roll over onto his belly but he csnt get back so this means multiple trips into his room to turn him over...at 1am... is 7 months a regression stage or is he just like "I'm gonna piss mumma off".... I was just getting used to the full nights sleep now I'm back at the zombie stage...health visitor said he should be getting 11 hours of uninterrupted sleep a night...I laughed and said well the only way that's gonna happen is if you give him sleeping tablets..cause he's bright as a button every 3 hours 😊 if anyone else is dealing with this issue please let me know... I'm contemplating strapping him down lol - that is a joke. See when he's 16 and won't get out of bed...I'm gonna play the bass drum 😂😂
