Ay, normal lang yan sis! Sa first months, ang babies natin talaga ay may slightly rounded or protruding tummy because their abdominal muscles are still developing, kaya parang putok-putok ang belly nila. One of my mum friends was super worried din about this with her first baby, pero the pedia assured her it's totally fine as long as baby is gaining weight properly, feeding well, and hindi siya uncomfortable. Para makakuha ng peace of mind though, it's best to ask your doctor directly kung concerned ka pa rin, they can check kung normal lang talaga or if there's anything to watch out for, especially kung may other signs like excessive gas, bloating, or feeding issues. Pero most likely, you're okay na!
