B.S.
My son loves Beets
I boiled them and then blended them. At first he was just interested in them because of the color but then he would yell when I would not feed it to him quick enough. But remember not to feed to much as you may find a red color in the diaper. He is not bleeding inside its just the beets.
My trick for other foods is to use organic maple syrup in foods that may be too tart. When I do apple sauce I add some organic cloves and organic cinn.
Oh almost forgot, my son loves strawberries. I cook them down then strain them using a nylon to get the seeds out. If its to tart I use a little maple syrup.
(all suggestions are with organic foods only)
