Length of time between feeds okay?

[PumpkinZulu]

So in stark contrast to my last bf thread, DD has gone from eating hourly to 2-3 hourly! Sometimes even 4! She's just come through a wonder week and is doing a stack of new things, as well as sleeping during the day. I'm so used to feeding every hour that it's hard to remember what it's like to have all this extra time I am still offering boob every hour but she just refuses now. So I guess my question is, at her age (4 months) is 2-4 hours between feeds okay?

ETA should have been, sleeping MORE during the day.
