I BF exclusively but have tried once or twice to feed DD a bottle of formula at night to see if she would sleep longer but she only took 3 and 2 ounces so it didn't do much, but if I were to get her to eat more, does it really work? I got scared off formula because DD was constipated for 3 days and on day 3 it ALL came out!
Also any tips for a smooth, no constipation transition to the one bottle of formula:?
