Hi mama! Lip tie is when the tissue under baby's upper lip is too tight, kaya mahirap siya mag-latch properly sa breast or bottle, nakikita mo kung parang may shortened frenulum underneath. A few of us in the mum group had babies with this, and honestly it can make feeding really painful para sa mama and baby won't gain weight well kaya best to check with your pedia or lactation consultant para ma-assess nila talaga. They can tell you kung kailangan ng tongue tie release or anong options available, pero sobrang importante na evaluated ng professional dahil may procedure involved.
