Aw, yan talaga ang challenging part ng first year! One of my mum friends swears by mixing the new food with something she knows baby loves, like pureeing veggies into the viand they already eat, kaya hindi napapansin ng baby. Also, a few of us tried offering the same rejected food multiple times in different ways (steamed vs. mashed vs. mixed in rice) because sometimes it's just the texture, not the taste! Patience lang talaga, sometimes they need exposure 15+ times bago ma-acquire ang taste.
