Your DD needs to check out flexible working, as she is entitled to request this with children under five. Shorter work breaks or use of leave days (eg using one 8 hour leave day divided up into 16 x 1/2 hour slots) so she can start 1/2 hour later, would probably resolve this for her without you having to put yourself out.
Is there such a thing as delicious ready meals?
Shall we reboot our cartoons thread again? 😁
