my doctor told me to start with veggies first not fruit because they will like fruit more and not wanna eat veggies and also start with green veggies then yellow and orange @beckka23

oh cool thank you so much c: can it be fruit flavor?

Yes you sure can. Start off with one flavor for a day or two to see how they adapt to it and how it affects their body. It's good to do this with each food you plan on introducing so if anything happens it'll be easier to narrow down which food it was.
