Ay, based sa experience ko with my kids, karamihan ng babies need burping until around 4-6 months pa lang, especially pag breastfeeding or formula feeding pa sila, kasi prone pa sila sa gas, pero honestly, every baby is different! One of my mum friends' baby needed burping til 8 months kasi maingay talaga ang tyan niya, while my second one was fine after 3 months na. Best talaga kung i-monitor mo lang, if nakikita mo na walang gas bubbles or comfortable na siya without burping, pwede mo na ma-ease off gradually, pero some mums namin I know continue pa rin occasionally kahit older na. If you're worried about gas or spit-up, better check with your pedia din para sure, okay?
