Now, you and I both know that nursing & sleeping are more important than jumping, but your DD doesn't know that. She just knows that when she asks to nurse you listen and when she asks to jump you don't. That's not something you want to teach her. So, instead, teach her that when she asks to jump she gets to jump and when she asks to nurse she gets to nurse.
Hmm... the thing is, we do give her plenty of jumping time too. Actually, the only times that we will turn down a request to play, read, jump etc. if it�s either her bed time (i.e. she�s clearly very, very tired but is using it as an excuse to stay awake longer) or if we�re busy like trying to eat, leave the house etc. Normally, that�s a pretty small portion of our day in general, so there�s plenty of play time in between!
