Aww, a year na pala, that does sound concerning! Honestly, I'd really suggest getting your little one checked by a pedia or an ENT kasi geographic tongue usually has specific patterns and may need proper diagnosis, maraming skin conditions sa babies na similar ang appearance pero different ang treatment, and since it's been growing, better safe na. A few of us moms din had tongue concerns na akala namin serious pero naging simple lang pala, pero kailangan talaga ng professional eye to know for sure!
