My baby (about 7 weeks old) loves his salad. I alternat between kale, chard and collard greens. Occasionally mix in a little broccoli, parsley or bell pepper (always tossed with his calcium powder). He also has a very healthy appetite for his bugs, so he's not just filling up on salad. My question is do I let him eat as many greens as he wants or do I limit his veg intake until he gets older?
