What do you do with your dear daughter during weekends? Maybe you'd like to plan activities with your kids during the weekends, eg bring them to swim, the playground, the library, etc.
Knocking off earlier is definitely good. And besides giving her biscuits and putting her to bed, is there any activity which you do with your daughter? Eg, give her a bath when she reach home and play with some water, read bed time stories, etc.
