When my little one was born, I had every intention of breastfeeding exclusively. But that was unfortunately not a possibility for us, so we had to start supplementing with formula. Being someone who is concerned about chemicals in products, especially those for children, I spent a lot of time reading up on different formulas. Eventually I decided to go with Earth's Best since it is organic, reasonably priced, and (unfortunately) one of the very few organic formula options out there. I hated that I was unable to breastfeed my little one, but she did really will on this formula. She did tend to spit up a lot, but she even did that with other formulas so I think that she was just more prone to spitting up than others. Even after being formula fed most of her first year, my little one hasn't has any real health issues. She has never really been sick and she has no physical or cognitive development problems at this time. While I do believe breastfeeding is more beneficial for babies, having formula was a life saver for us and Earth's Best was the one we used the most.
