Hey mama! At 11 months, kung noticed mo na may problema sya sa pagsuso or pagkain, best talaga to check with his pediatrician or maybe an ENT kasi they can assess kung may lip tie talaga, sometimes it looks like may tie pero okay lang ang baby, other times kailangan ng intervention. One of my mum friends had this with her son at after frenectomy (ang procedure para ma-release ang tie), mas smooth na ang feeding nila, pero importante talaga na expert ang mag-assess first bago mag-decide kasi may risks din kung unnecessary, you know? Wishing your little one well po!
