I apologise in advance that this is long and complex. We use a local CM for our two DC, one of whom will start school this summer. We're generally happy with her, and she's been brilliantly flexible and accommodating.
Until now, I have worked two set days and then some extra hours which I worked around DH's shifts to save on childcare costs. We therefore booked the two days with the CM, and sometimes DH is sitting at home on a day off while the DC are at the CM's - in the last fortnight we spent £170 on unnecessary childcare. We have just accepted this until now - we assumed she'd expect set places to be booked so that's what we did.
My work have now asked me to set my extra hours rather than use them flexibly and because (due to DH's shifts) we'd only need extra childcare for two out of every five weeks the CM thankfully agreed to take the DC for these two without us paying for the space every week.
My problem is that now this is in practice it's just not working. Our budget can't accommodate the extra costs and I'm actually struggling to have enough money for groceries this month (and I am pretty frugal as it is), next month's not looking any better. Obviously in the summer everything will ease as my son goes to school but until then we are going to get in a huge mess.
Would it be massively unreasonable to simply explain to the CM that we can't go on as we are and ask if she would consider taking the DC on an as required basis? I can give her months of advance warning about which days we'd use. Or is this just a ridiculous request which will insult her/put her in an awkward position, and I really need to review my work situation?
I am so down about this and can't think straight for panicking about money - any suggestions? :(
