A friend of mine is utterly stuck for childcare for 3 days in Aug (her CM is on hols, work won't let her have both weeks off and she has no family help). She's a single mum who doesn't earn much and I was wondering whether I could ask our nanny to have the little boy for the two days she does for us. The week in question she won't actually have my two older DC as they are off staying with MIL that week so it would just be the nanny and the baby (he'll be just 1 by then). There would be no school run to worry about and my friend would drop her son at our home and pick him up again. Is it appropriate to even ask our nanny to do this? Are there any special rules about looking after children other than those of your employer (even if just for a few days)?
Thanks!
