Brummieontherun you made a mistake by allowing your AP to stay in bed in the morning while you did everything for 3 children. We all get it wrong with our first AP but we learn pretty quickly - absoluely make sure your clear about this with your next AP.
For what it's worth - here's what I ask of my AP's (I'm on my forth now in 3 years so consider myself not quite as green as I was in the beginning).
7.30 - 8.30
Wake DC, make breakfast, make lunchboxes, clear away kitchen and sweep kitchen floor.
8.30 - 9.30
I take DC's to school and AP spends an hour cleaning their bedrooms (2 bedrooms and 1 bathroom) and putting any of the DC's washing on.
Free till 4 when we arrive home. AP them helps with laying table (I cook dinner) ,any DC's ironing, taking DC's to activities, clearing table, putting clean uniform out and generally playing with them and helping (together with me) with homework
I always say to AP's they don't have to do anything for DH or me - only the DCs, their laundry, bedrooms etc and they seem to think this is quite fair - it also helps to be clear about what they do and what you do.
Re: the morning. They are all without exception lazy buggers who for reasons best known to themselves always ask me if they can go back to bed after I take DC's to school and before they clean the bedrooms. My answer - no. Clean the rooms then the rest of the day is yours and I also let them go out nearly every evening and they have week-ends free too.
Hope this helps clarify things.
