What different ways are you trying to burp?
My LB has been awful with burping every since he was born he’s now 3 months and we use 2 infacol in every single feed and he burps so good now, i found putting him on my shoulder straighten his legs and between his shoulder blades I do the figure of 8 and within 1/2 minutes I’ve got a massive burp up! Obviously all babies are different but that’s what works for us, hope you find the best way for you and your LG x
My little ones always been stubborn and refuse to burp then spits up 🙃 then a couple hours later she’ll randomly burp it out herself
