Ds1 goes to the nursery attached to his school. Another mother who works two full days a week has asked me if I would, on those days, pick up her son and drop him off at his private nursery which is practically next door to ds's nursery.
I have said that is no problem but will need her number in case on any given day I can't make it. Her ds appears to be very well behaved. I can't see any problems with this arrangement but just want confirmation that I haven't missed any potential problems.
