Fundraising for my babies headstone.?

No there is nothing wrong with that. Headstones are very costly and many people have a hard time covering all these cost. Most people would be happy to help you. My sister in law was young and her father ped. She had taken a loan out but of course that didn't cover all the cost. So she asked local businesses to donate anything they could (anything even napkins and plastic forks, spoons, plates.) She held a dinner at a church and the plates I think were maybe $10.00 A company donated about 12 pigs for a pig picking and people baked cakes and other foods to help. It was a success. Even the fast food restaurants helped. Just call and ask. If you do this you would have to make fliers for and get tickets for the door. A printing shop may donate those to you. I hope you do and I'm so sorry for your loss. Best wishes to you.
