As anyone who reads me knows, I am very pro-breastfeeding. But I am not anti-formula. Ella ~never~ got formula, but I eased up with Allison, giving a supplemental bottle every now and again when needed.
Well, the other night I was exhausted and was heading to bed and Karl had been "snack nursing" and was hungry. I was too tired to feed him yet again, which wouldn't fill him up since it had only been maybe 45 minutes to an hour later, so I just went in kitchen, opened a can of formula I received in that gift bag thing from hospital, and made him a 4 oz bottle, which Tom later said, he finished.
My baby slept for 4 hours in a row! The most he slept continuously so far in his life had been 3 hours.
I had read that it's a fallacy babies will sleep for longer periods regardless of if they drink breast milk, formula or if someone actually puts cereal in a bottle at such a young age. It's true these different meals will digest differently, but sleep time had been proven not to change.
Now, it makes sense to me that if you are not as hungry, you will sleep longer, but the point of the study showed there was no difference. But I definitely saw a difference, but it was just one time, which a scientific conclusion it does not make. (I'm speaking Yoda.)
What about you? Do you see differences in your baby between feeding breastmilk and formula?
