My own feelings exactly, Sel and my DD and DDiLs agree. But then we have never lived near any of them while the children were / are small. We are very happy to drive up to Hampshire or Gloucestershire to babysit, though.
We now live very near to DD, but her children are 17 and 15, so calls on us usually involve lifts etc. but I have done both children's Parents' Evenings, as my DD teaches in the same school, and DSiL says "At least you know what they're talking about." and if she has a meeting, then they pop round here, and we take them home after a bit of spoiling.
