What kind of juice do you give your babies? We were told she could start on juice at six months (she's almost 8mos). I'd prefer to stay away from anything that has a lot of sugar or added ingredients (like the Gerber juices lmao). And how much do you give them? I'm thinking that giving her small amounts of juice when I give her baby food would help introduce a sippy cup better.
