As a trained chef and creator of Weelicious, a website (weelicious.com) dedicated to healthy eating for babies, toddlers and kids, I’ve learned that one of the easiest ways to add extra zip to homemade baby food is with herbs and spices. One of the first vegetables I offered my son, Kenya, was puréed butternut squash. Much to my chagrin, he rejected it on the first three tries. But on the fourth go-round, I added a pinch of pumpkin pie spice and, voilà! He gobbled it up.
