It varies so much from baby to baby i dont think you can say how many times "most" wake for a feed at a certain age. My LO slept through from 4 months then stopped at 5 a couple weeks ago he was getting up at 1am and then hourly until getting up for the day at 5.30-6.30, now he has started just getting up once for a feed around 3 or 4.
For me at least it has changed so much from month to month or even week to week!
I've grown to hate these threads I want five hours continuous sleep
