Toddler refusing bottle and straw cups

Need help or tips pano mapadede toddler ko, kapag milk po yung bottle kinakagat niya lang, yung straw cup hindi sinisipsip or sobrang konti lang, pag pinapainom sa baso iniipon sa bibig tapos iluluwa din. Tried diff bottles pigeon, avent, comotomo and tried diff milks, enfa, bona, lactum. Pag tubig naman pinapainom thru baso and straw nauubos naman. Mostly breastfed si baby and 2x a day lang nag bobottle feed per day. But now nirerefuse niya na any form of formula milk :/ Thank you
