Is this gonna be forever ?

Lol I’m just kidding with the title but did anyone’s baby start waking up about once a night around 6 months and hasn’t stopped yet? We were sleeping through the night from like 7pm-6am but right after we hit 6 months he started waking up about once a night and wants to either be rocked and held til he falls back, or sometimes needs a bottle (he sleeps through still sometimes but it’s like a couple nights a week only) but I’m just thinking is this now the routine we’ve made and it’s gonna be this way for a while unless we do formal sleep training? Or could it change on its own? Anyone with other kids have any words of wisdom on this? Ty
