Is it bad my 2 months old baby is sleeping all night?

NOPE. My Son has been sleeping through the night since 1 month and a half. At that age, formula (not sure about breast milk) fills them up more and they sleep longer. Your baby will cry if she/he is hungry. If not, let them sleep :)

    Jealous!!! All three of mine started sleeping through the night right away - like 3-14 days old... but all three STOPPED sleeping through the night around 4-6 months and none of them have started back up yet!!

    Mason and Audrey will sometimes sleep the entire night, but usually they wake up at least once. Hayden I guess technically sleeps through the night, as she goes from 7pm - 4am, and then wakes up to eat and goes back to sleep until about 7 or 8.

      Our first was sleeping through the night at about eight weeks but none of the rest were and that was fine with me because by that time I had figured out nursing through the night was ok.
