I have two children DS 3.5 and DD 1 and look after a little boy three days who is aslo 1. I have a variation for this as he has been with me since they were 5 months.

I have been approached by a mum who wants two days from September and increasing to 3 in January when DS is 4.

Is this allowed and would it be ok if it was on the day he is full time at nursery?
