I've been fortunate with my family and friends. I'm going to launch my kickstarter this week and many of them have committed to getting onto kickstarter and pledging at the 1$ level, some have already expressed a willingness to pledge more.
I think the most important thing to get family and friends on board is to explain that it's not about you asking them for money, it's about them helping with "social proof" the phenomenon that keeps people from getting on board until they see others getting on board. I've explained to my family and friends that this is something that really matters to me because of how much time and effort went into it, but the thing that really helped get them to agree that they'd show up for me is when I explained the concept of social proof and how it affects kickstarter campaigns.
It's like a light went on and they understood that their participation could make a 'real' difference in the outcome. I think a lot of normal people who've never learned anything about marketing assume that an idea/product will succeed/fail based on the quality of the idea/product and don't realize how many other factors are involved.
Afterthought, here's my kickstarter:

It's a mobile math flashcard game that I made using the game engine Phaser3.
