Ay, this is tricky kasi ang pedia mo already gave you the feedback na it's not typical for 2-month-olds, usually they should be pooping daily, especially if breastfed, so I'd really follow up with your doctor on this one, maybe get a second opinion kung kailangan mo ng peace of mind. A few of my mum friends had similar concerns at that age and turned out their babies needed adjustments sa feeding or may minor issues na kailangan ma-address, so better to check sooner rather than worry, di ba?
