Hard to burp

I stopped burping my baby after 1st month cause it’s very hard to burp her as well. I can be burping her in all different ways for a good 20-30 mins and still not burping. What I do is after feeding I’ll stay her in the same position (be it whether she’s lying down/on my arms) so that I won’t shake her (in case she throw up) for 10-15mins. Then I’ll lay her in tummy time position and she’ll burp on her own. Works everytime 😊!
