7 week old eating habit

Kristine

So my son is 7 weeks and eats so much! I breastfeed but usually pump and give him a bottle. He usually eats 4 oz every 2 hours or so sometimes every hour but yesterday he ate so much! He ate 6 oz in one sitting in the afternoon and 8 oz (!!!!) before bed (2 bottles) and one bottle even contained some formula hoping it would fill him more. I’m nervous he is over eating. Am I over reacting or does anyone have any advice?
