Sudden Appetite Changed

Hi po, may 1 year and 7 months po akong baby boy, magana na sya kumain e yung tipong kada meal nya may meat, veggies, rice at fruits at halos nauubos nya lahat, pero recently lang mga 1 week na syang halos ayaw kumain at puro prutas lang. Tapos ngayong araw halos walang kinain, puro breastfeed lang sya sa akin. Anu po kayang nagyayari? He seems ok naman po at energetic.
