Need some advice - frustrated.

So some background....
The wife of someone DH works with has been looking after our girls 4 days a week since I went back to work nearly 2 years ago. The agreement has always been that she would work Mon - Thursday 7am - approx 5.30pm (usually the girls are picked up at 4pm so earlier than agreed but she still gets paid the normal amount. with the occasional friday in there also. If she works 4 days I pay 4 days if she works 5 she gets paid for 5. The agreement was that at anytime if need be days could be swapped around ie. if she is sick on a Wednesday but well on the Friday she would have the girls on the Friday. So she is still working 4 days and being paid for 4 days. There were quite a few days that she asked if she coul.d swap at the end of last year because of various school events etc - no problems.

So, i am having a couple of issues now....

First - being that this weekend is Easter and I have a course on Friday I asked if she was happy to swap MOnday and Friday for that week ie - she works Tue - friday instead of mon - thurs. For her that wasn't an issue until today when she now wants to be paid for the full 5 days - even though she is only working 4 days.... I'm frustrated because i have happily swapped my work days around for her when needed (despite how cranky my boss gets when i ask) but I ask her to do the asme and she now wants to be paid for 5 days!!!!!! I have always paid her if she has been sick and i've still had to take the day off work, I gave her $150 bonus at Christmas time - damn, i even paid her a full weeks pay when my kids were at thier grandparents for the week!!!!

Second, despite our agreement being that she has the girls until 5.30pm she told me 2 weeks ago that on a Wednesday the girls need to be picked up at 4.30pm AT THE LATEST. I don't finish work until 5pm and I work 45mins away!!!!! DH isn't alway able to get them at 4pm. So again - i go back to my boss who agreed to let me change my hours so that i can pick them up at 4.30pm - at her request.


I've looked over allot of things that frustrate me about her... eg... she complains shes got no money except she is taking my kids to the movies every other week and buying them shoes and clothes (apparently i'm incapable of providing this.....grrr). I have never aksed her to do this, in fact i gave her siggestions on free stuff to do with them eg. the park, rhyme time at the local library. I provide ALL the food for the week (1 loaf of bread, about 4L of milk, biscuits, ham, yoghurt, a box of cereal each week, fruit, museli bars, i send treats occasionally for them, leftovers for lunches EVERYTHING. Yet still says they eat her food also.

I feel like saying thats fine if you want to be paid for the 5 days, but next time you have a sick day and I have to take the day off work you won't get paid.
Am i being unreasonable? I can't afford to pay her 5 days next week (shes only working 4 days) but she is pushing for the payment.
