What do you think? A mother whom I barely know (met her at open day, exchanged contacts at my instigation, and since then met up 3-4 times) says she knows someone who can pick up our children after school in the autumn and look after them alternating between our two homes (about 30 mins' walk apart) and wants a quick answer from me. She says this will be much cheaper. My other option is an after school club, which is quite expensive but cheaper than getting an au pair, and I feel more comfortable with it being a club with more than one worker, so the childminder's sickness would not be an issue for me. I am also inclined to go for the after school club because it will be more fun and friendly for ds, and not to be too dependent on another family. Should I be jumping at the chance to save some money like this, or am I right to be worried that we would fall out?
