My LO just stop drinking milk

Hi mommies and daddies! My LO, who is 1yr and 8 months, just does not want to drink milk. I tried tricking her in different ways na para mainom nya yung milk nya, pero pag nalasahan na nya yung milk, ayaw na nya. Masigla sya kumain. Kahit ano kinakain nya except fruits. Hindi ko alam pero di sya mahilig sa matamis kaya di rin sya nagvvitamins. Nagsimula to nung nagka something sa poop nya kaya nagantibiotic sya. After that, ayaw na nya nung milk. Im so worried lang sa nutrition nya if baka nagiging kulang na. We’ll consult pa sa pedia pero I would just like to ask you po if may ganitong phase din po babies nyo or any tips po to make your LO like milk again. Thank you.
