How often is you little one eating?

I’m going to start by saying he has HORRIBLE reflux and is on Zantac 3 times daily. I’ve been home with him up until the 11th of this month. He’s ALWAYS ate every 2-3 hours. He’s almost up to 6oz now and sometimes he will only make it to 1:45 mark before he’s hungry now days. I don’t want to increase the amount because him spitting up. His daycare has been complaining because he “needs to eat every 3-4 hours instead of 2-3 hours”. He’s a nice sized little fella and even with reflux he’s had NO trouble gaining (🐷). Any advice on what I should do? 😩

Picture because, well because...he’s cute. 😂🥰
