I have always given dd what we call the "midnight snack" at around 11:30 or 12:00 at night. She used to consistently wake up at around 4 a.m. to eat again, but the past few nights she has slept through until 7:30 or 8 the next morning! Of course I'm not sleeping because I keep my ear on the monitor to see if she is waking up! Is this normal? She's almost 3 months old, eats about every 3 hours during the day, pees a lot and poops a couple of times a day.
