Hi R.,
I have an 18 month old baby girl, and when I had her, I wanted to breast feed only. Unfortunately, I have closed ducts, and the milk could not come out. By the 3rd day she was born, she had to eat, so I had no other choice than to put her on formula. I felt horrible, because of this, but like I said; I had no choice. I had her on formula until she was 9 months. The pediatricians will tell you to go to the year, which I would have, but one morning, as I was preparing my baby's bottle, I got a gut feeling that something was wrong. This gut feeling was so strong, that I didn't give the bottle to my baby girl. Instead, I got online, and started to research each ingredient the formula had. I checked for the side effects, and let me tell you, my daughter never drank formula again. All the closed containers I had, I took back to the store and exchanged them for organic milk. I don't want to scare you, but to at least suggest that you find out what is in that formula. First find out what it is you are giving your baby. Once you know, and are 100% sure that is safe, then feel free to give it. My advise is that if you are able to breast feed, do so. Avent sales a manual pump that you can take to work with you, and every hour or two you can step into the bathroom, and get milk out for your baby. Breast milk doesn't go bad for a long time, but if you feel worried that it could go bad, just keep a small cooler in your car. Always go for what is best for your baby, even if it gets inconvenient for you. Now, if you think you made the right choice, then there is nothing you should worry about.
- Good luck!
PS- A great alternative to breast milk is Goats milk. - you can find organic goats milk formula at a health food store.
