Hi po. Ftm here! Baby ko po is now 1 year old and she us not drinking her milk po kasi nag switch na kami from 3-6 months na milk to 1-3 years na milk, same lng nmn yung brand and now ayaw nya po talaga uminom ng milk, 4 days na. Nag try na po kami ibang milk pero ayaw padin. Please help po! Ano po pwede ko gawin? Naranasan nyo na din po ba ito? Huhu Salamat po sa tulong. #advicepls #firsttimemom
