Go in, cuddle DD. Look at them while they are sleeping & remember how much you really do love them.

Maybe you could give DD a special box. Have a book & some nibbly food & a few toys in there. Change the contents every day & when you need the 10 - 20 minutes to do those things, go sit her down give her the box & let her find the suprises in there.
Use the same toys etc, just swap them around every day
