Ladies how much is your 5.5-6 month old drinking? Mine drinks 6 oz every 3-4 hours but he’s also very random like he will go hours without eating in the morning but pigs out in the afternoon and evening. I’m wondering if I should up him to 8 oz. he sucks the bottle dry when he’s taking 6 oz...only issue is I use dr browns and it specifically says if u go over the 8 oz marking they will leak. Does anyone use dr browns and they go over that line and it doesn’t leak? So basically if I up him to 8 oz I have to buy new bottles. Just looking for some insight and advice. Thanks!
