What an amazing display of opposing principles. Totally agree with the person who said there "isn't a general rule" - and whatever some people might have felt happy doing has nothing whatsoever to do with what other people are OK with.
Just to add - the remark about the messy kitchen definitely says anxiety to me - whether PND, or common-or-garden sleep deprivation, or, possibly, even awkward recognition of how much less well she is managing then milliec clearly did.
milliec - I'd do total water under the bridge on this one, and give her a good long settling in. You may find she needs your support.
