My CM has told me she's had a complaint made against her for having too many children.
Her children are grown up and between them have 11 children so her house is busy if they visit! Her daughter is also a CM and sometimes minds children at my CM's house, and on busy days she will do nursery runs in the car (my CM doesn't drive) thereby saving all of the DC having to traipse up and down the road all day.
While the house is often quite hectic there's a happy, laid back atmosphere and my only grumble with her is that I think there's more TV and biscuits than I would allow at home - however, as mine only go twice a week I haven't brought this up. It would be something to discuss if they went more frequently.
She has agreed the arrangements involving her daughter verbally, and I have no problem with them - the way nursery sessions fall, DS would have to walk a 40 minute round trip, have lunch in 10 minutes, then walk another 20 minutes to go back to the nursery if there were children for morning and afternoon sessions in one day. At 13 months DD would be in a pushchair half of the day if her daughter didn't help!
She's asked me to sign an updated permissions form giving written permission for them to be cared for by her daughter too. There aren't going to be any problems with this, are there?
