Hi everyone! I really need some advice. My Fiance and I have been living together for 8 years. We are getting married this October. Since we have lived together for so many years we have all of the necessities that we need. Next year we will be trying to have a baby but unfortunately we have to do InVitro (IVF) which will cost us $25,000.00

In additon we are paying for our wedding completely by ourselves. How would we word it on the invitation that money would be appreciated instead of gifts (without sounding tacky). This would help us out a little with our baby planning next year. We are having an intimate wedding with family and close friends only. Thanks for any suggestions!
