I also agree with MON and Breakaway. It's time to enjoy the success and sustain the gains for awhile. Life is a journey - as long as they continue to make gains, learn and progress, they will have the opportunity to learn challenging skills and develop their knowledge base. It's not like the clock will run out (hopefully).

And you know, it is not a sprint for you, either. This parenthood thing is a marathon. Sometimes it makes sense to slow down the pace, get a drink of water and coast for awhile.
