I know little Ryans only a week old, and we think he's in his growth spurt!!! But he feeds about 12, 3, 6... The midwifes in hospital told us to try and stick to a 3 hourly pattern so maybe he's gotten used to it. If the times change though so he does a 1 o clock and a 4 o clock, we tend to leave him asleep til 8 or 9 if he doesn't wake before then, just so we can have a bit of a kip!!
