If baby is drinking formula milk in the middle of the night. Do u wipe his mouth after drinking or continue to let LO slp thru?

If lo has teeth, then the normal brushing twice a day should be good. I do let my lo drink some water too throughout the day to just rinse off the leftover milk. I think it's actually quite hard to wipe the mouth while he is asleep. Important thing is not to leave the bottle in the mouth and let the formula pool in his mouth. He should finish his milk and swallowed everything down.
