Ay, alam ko yan feeling na mama! Mine was the same at 2 years old, and honestly parang lampas lagi yung tiyan niya compared sa iba, a few of us mums were worried din, haha. Pero usually normal lang yan especially kung active siya, kumakain ng maayos, at ang poop at pee niya normal; kids na ganyang edad often have little pot bellies pa lang kasi ang core strength nila ay developing pa. Pero pag worried ka talaga or kung nakikita mong something feels off, better to check with your pedia para maging sure ka na, they can give you peace of mind agad!
