Night sweats

I’ve been having night sweats starting sometime after giving birth which I read can be normal. However my child is now over a year and I’m still experiencing them just about every night. I had my yearly physical and my physician didn’t seem to be that concerned since they’re not every night like when it started. But she also mentioned that usually only lasts a few weeks and is closer to when you have birth. I’ve bottle fed the entire time as well so there wouldn’t be anything related to stopping breastfeeding since I never started. Has anyone experienced something similar?
