Quickly scouting for opinions while the babies are napping.....
I am a CM and started with a new family in Sept. When we did the contract, I expressed I like having Mondays off in school holidays (as the other 2 I mind on a Mon are Term Time only). Therefore could we have an arrangement of Mondays also being Term Time only. Gives me a long weekend and enables me to spend time with my own DCs.
New Parent wasn't budging and cornered me into agreeing to working 5 days a week in the hols - regardless of the fact I will only have their child on a Mon in the hols, no other mindees.
I should have said 'No', I know this now 
Anyway, Half Term next week. Both parents are off work for the week. Not going away - just catching up around the house. Child still coming to me for their days of care. No issue with that, but I am annoyed that I couldn't pre-plan my Mondays off. Surely they could have covered it long term?
2 Parents on leave; child coming to me when we already discussed my requirements.
I'm not working over Xmas so that isn't an issue now. But can I be brave enough to say 'actually, I have been thinking and I can only offer Mondays Term-Time from January'.
Please tell me I'm not being unreasonable with my request
