Ay, nabasa ko to sa ibang moms din actually, around 3 months parang ganyan talaga, biglang maraming poop tapos may seeds pa haha, but this is something worth checking with your pedia since bumasa ka ng ganitong biglaang change, lalo na kung may greenish tint pa. One of my friends' baby had similar and turned out okay lang, pero better safe than sorry talaga, especially pag parang ipot ang consistency. Keep an eye kung may iba pang signs like fussiness or hindi kumakain ng maayos, then go straight to your doc. Rooting for your LO!
