DP would/will get up nights where he doesn't have to be at work the next morning ie. Friday/Saturday OR if there has been a spew etc to help clean up (I'm really, reallly bad with vomit).

However, when i also went back to work this had to change as I couldn't be tired all the time either so it went back to being a shared thing. The good thing with DP's job is he gets heaps of carers leave so he always stays home with DD if she is sick
