My LO is 17 days old now and will mostly wake up after every 3 to 4 hours for a feed (usually 3 1/2 - 4oz) but if she doesnt wake up before 4 hours am i still meant to wake her ? I was told by mw that i was but that was a week ago and i dnt know whether im to carry on doing that or to let her wake when shes hungry? Any ideas ? x
