Baby refusing bottle feed at night

My 7 months old and the last 2 nights he’s refused his bedtime milk. Last night he didn't have a drop, just didn't want it. Yet slept through an extra 1/2 hour than normal??

Tonight barely took 2 oz's then didn't want anymore of that.

He takes, before bedtime bottle, usually8 oz of formula per day plus breastfeed. He also eat at least 2 or 3 times solid food.

I *think* it may be teething but heck I've been blaming that for aaaaaaages now and still no tooth through :lol:
