Did anyone else’s baby have trouble sleeping when switching from formula to whole milk?

My baby will be 1 on the 17th this month and we’ve begun transitioning him to whole milk. I thought he was done with sleep regression, which started I thin over a month ago but his regressions last at least a month, not a couple weeks like they say they’re suppose to. Anyway, he started sleeping normally again and then we started transitioning him cause it seemed like he was trying to wean himself from the bottle but tbh idfk. This is all so confusing. He’s been teething through his sleep regression too so idk what the cause of anything is and the pediatrician is no help. I’m going insane over here trying to figure out what the heck is going on with him.
