i like a dog training show on tv. i forget the name but he had this problem on the other day. he said not to give them attention cause that is what the jumping on you is getting them. that is what they want. instead when they jump up hold their front paws and look away from them so they are not recieving the attention.you don't need to start out holding for long just be consistent each time they jump. when they sit then give them a reward. that would be rewarding them for their good behavior. he used small treats that the dog liked. when they had a follow up it seemed to of worked. but everyone in the family needs to do this and be on the same page. good luck.
