I remember reading a study many years ago that found that about 80% of babies "sleep through the night" at around 3 months, and that at 6-7 months most of those babies begin waking again several times a night! It is not related to breastfeeding, just normal childhood developement! My first, my only crib baby, I would find practicing new skills, like pulling up in the wee hours. The rest I have just nursed back to sleep before they are fully awake. When parent say my baby "slept through the night at 2 months", they don't tell you it only lasted a few weeks.
