Kiara • Queening. 👑 Mommy Of One BabyBoy💙

My child’s a tuff burper I guess ...

He drinks 4oz of milk. And I will burp him after 2oz and then 3oz. Then I’ll try and get the last burp out at 4oz BUT he always acts milk Wasted and sleep. I switch burping positions and all and he be SLEEP then have bad gas later. What should I try ? He literally outta a 4oz bottle will only give me 2 burps before he sleep but will almost never burp after the bottle is finished 🤦🏽‍♀️ any suggestions
