Ay, I totally get it, picky eaters are a real challenge, especially kapag may autism kasi mahirap mag-adjust sa bagong lasa! A few of us sa group namin na may special needs kids, nag-try ng regular whole milk mixed with Pediasure para ma-gradual ang transition, or some moms swear by Ensure or Sustagen kasi medyo similar ang taste pero lighter ang tummy effect. Pero honestly, best talaga na i-ask mo first si pediatrician mo, lalo na may autism siya, para makasiguro na aligned sa nutritional needs niya at walang issues sa digestion, baka may specific recommendation pa sila based sa health niya. Good luck, mommy, I know how hard ito!
