Anyone else's LO night feedings all over the place?

I see a lot of people on here where their babies will wake for their night feedings at really reliable times like clock work but my guy is all over the place. Nothing is consistent. Some nights the first stretch is 4 hrs, sometimes 6, rarely more. The second is either 2 - 4 hrs usually depending on the first stretch.

My husband and I are still doing sleep shifts because I really want a time to sleep where I'm not waking up from the monitor static every time LO moves in his sleep. And especially since it's always a mystery how long I would potentially get cause I always get my uninterrupted sleep during the first stretch.

Edit: forgot to say LO is 5 months
