To not want to take neighbour's children to school everyday.

[3duracellbunnies]

She is doing training course, he works away a lot. Aged grandparent helps with childcare but not up to doing school run twice a day. They are fairly spirited boys and don't always listen. With parents they run on 3-5 mins ahead, I don't let them. I have dd1 in yr2, dd2 yrR and ds(2) who has just started to want to walk some of the way. We do walking bus 2x week, so can only take them those days if they sign up too and parent walks on bus once a week. Am I selfish to say that they should go on walking bus everyday even if we still only do twice a week? No money or reciprocal childcare offered. My girls prefer not to share me and is nice time to catch up with them.

I really understand the bit where you say that your dds like rme with you. I tried a reciprocal arrangement that should have been fine but I discovered that dd wanted her time with me more than I thought, not to mention the fact that taking an extra one and waiting for her to arrive each morning was not equal to the benefit I gained from not having to pick up in the afternoon. Anything, almost, for anyone, almost, as a one off or emergency. Regulars don't work for me although I wouldn't rule them out if and when I return to work.

I must admit I have had a lot of help from friends and neighbours with befor and after school care over the past few years, as the only childminder in the village was at capacity, and the holiday/out of hours club shut down when the 2 ladies who ran it both got pregnant at the same time!
I have always tried to help out when I can in other ways, ie childminding onmy days off, lifts if required, doing shopping etc.
It is a give and take thing, and your neighbour should offer to help out if she wanted you to continue. Get them to sort out the walking bus, then you will no longer have this to cope with.

YANBU.
Just say no, that taking all five of them is to difficult for you and that she should find alternative arrangements
