Stoping night waking

Okay, so I seem to do nothing but beg for help for you guys every time something changes in my LO.

To be honest it sounds like he is terrible at sleeping but he really isn’t. We have a wonderful bedtime routine, he has white noise going, he sends himself off to sleep all by himself for naps and at bedtime and, currently, when he wakes up during the night I stick a boob in his mouth for 10 mins and he is ready to go back down (apologies if that is crass). The problem is I have had over a year now of getting up all times in the night and I just can’t take it anymore.

We tried changing to his dad calming him and putting him back down but it took a really long time for him to go back down, whereas it only takes me a maximum of half an hour.

Whenever we look online for help it talks about routine etc but he has a great routine and independently sleeps great, he is just waking up during the night.

We have a video baby monitor so I am going to get it to record during the night to see if there is anything waking him up but other than that I am at a loss.

Any ideas to get him to sleep through the night?
