Aaah mama, totally normal yan, EBF babies can be super picky with formula kasi iba talaga ang lasa ng breastmilk! A few of us mums tried switching bottles, using a cup or straw instead, or even mixing a tiny bit ng formula sa breastmilk first para ma-adjust niya gradually sa taste. One of my friends swears na mas okay ang mainit na formula at biglaan lang na inooffer, walang forcing kasi nakakasensitive ang babies. Since your lo is turning 2 soon, honestly you have options pa, pwede mo rin i-combine ang formula sa food like sa ulam or sopas if kailangan niya ng extra nutrition, pero kung purely for weaning purposes lang, marami pang time pa yan!
