Ay iba talaga kulani sa tenga kahit walang ubo sipon, nakakaworry talaga! Siguro lang check mo muna kung may earwax buildup or if something small got stuck there, pero since 10 months pa lang siya, best talaga to have a pedia or ENT check it out para sure lang, a few of us mums panicked din over ear stuff before we realized sometimes it's just normal baby ear stuff or something simple. In the meantime, don't poke around inside (nakakapainit lang kami don lol), just keep the outside clean. Let me know what the doc says, okay?
