Nope, I just don't see the point. I'd prefer not to be buying formula anyway because I don't agree with some of the corporate practices of the companies that make it, but I got sick and my milk dried up so couldn't BF anymore. So I certainly don't want to do it after 1 year when I can use cow's milk. There's a lot of fake, nasty stuff in formula and it's a great thing when you need it to meet the nutritional needs of your baby. But I'd rather buy some nice local milk and make sure my daughter is eating a healthy, well-balanced diet. We eat pretty healthy in our house, so I just can't see the point. I'd rather my money go to support a local farmer than to a big corporation. Plus, I've heard babies can't even absorb all the added nutrients anyway, so seems like a waste.
