I mix my baby's lugaw with kalabasa and she's liking it. But when I mix it with other veggies like papaya or sayote, my baby doesn't really like it. Do you observe this on your babies also?

Yes. :) I agree with Lucas that babies have different taste preferences too. Allow me to add these suggestions: -serve them in a way that will entice them to try it like using shape cutters to make stars, hearts, diamonds on so on. -Add a splash of color too by putting different colored veggies in a plate. -use their favorite plate or bowls and spoons -Sing a song or play a toy in front of them to divert their attention from the food in their mouth -Show them that all of you are eating it too to encourage them hope one or two from this list helps :)
