4 month old finishes bottle less than 10 min

LO eats 6 oz every 3 hours and usually finishes his bottle super fast. We’ve been using tommee tippee bottles with a medium flow nipple. We usually burp him after his bottle since he hates being burp during his feedings. Should we try to burp him every 2 oz and see if that helps him take a little longer on his bottles?
