So, along the same lines, should people start giving out sex manuals (I saw you gave one as a gag gift, LOL!), cooking classes or marriage counselling as wedding gifts? I totally get that people are trying to be practical and helpful, but telling someone how to spend the money you are gifting to them is just not a great idea, IMHO.
Young couples should spend time in financial and marriage counseling if they need to. They should, if they don't know how, learn to maintain a house, take baby care classes. Those are all wonderful things. But the advice to do those things to a couple starting out needs to balance two things. The first is that not everyone needs the same help - some people are well prepared to manage their finances, or have great homemaking skills. The second is that whatever advice you give to get help needs to be done in a gentle fashion. Saying to your brother and his wife, privately "I don't know how you guys manage your money, but I really wish Bob and I would have done this seminar when we first got married" or "if you don't have a financial planner yet, I like mine" or "I know the first year of marriage can be tough - if you find you need a therapist, Bob and I went to counseling with a wonderful woman early on" is about as much as you can do.
