I read on a "what to expect" email that babies around this age can stay up 2-3 hrs now. Mine can stay up maybe 2.5 and occasionally 3 but she's usually grouchy by then. Her average would still be about 2 hrs. She still takes 3+ naps (naps are not very long usually less than an hour) but sleeps about 9-10 hrs at night.
Anyway other sources say much shorter wake times, but I'm guessing it just varies by baby...so what is/was your LO's average wake time at around 5 months old?
Should I try to extend it, or leave it as is?
