Vegan Guidelines?

Okay so I have been wanting to go vegan for a long time now but my SO makes it IMPOSSIBLE. We live together and he HATES vegetables. 😫😫😫 I try to incorporate as much vegetables and fruits as I can but he was raised on eating meat with EVERY single meal. I was just wondering if any of you ladies had like a meal plan that I could try? I plan on raising my son vegan (he is still only 12 weeks old) so I’m hoping that I will be well informed and experienced before he gets to the age of eating solid foods! So any ideas or advice would be greatly appreciated!
