Baby wakes up more than 4 times for the last two nights. Help

He used to wake up 2-4 times every night, but mild feeds or rocking and lullaby would put him to sleep. He just syirs2 ans kind kicks and makes anow angels on the bed. He is lighrly2 dressed as it is approximately 25-30 degrees Celsius. He is fed semi solids around 7.30 pm. I breastfed him twice for a couple of times later. He just wails and wiggles and won't be silent until i offer to feed him. This happened all last night and I was sleepy in the office today. What is happening to him? His teeth aren't showing yet. Is it too cold? He sweats sometimes in sleep. I want to break the feed and sleep association.
