How did you know you were done having kids?

Obviously finances have a huge part. I just can’t get the future out of my mind. I don’t know where we will be, or how I’ll feel in say 5-7 years. I just love my babies so much, as babies 😂. I love them growing too but I’m just so in love with creating life, giving birth, and all the baby firsts. I believe parenting is the hardest job in the world, but I know it’s what I was meant to do. I currently have 3 kids, 2 from a previous marriage. 8 and 6. I met the loml and we have a 10 month old and I’m already starting to think of another, he’s such a great dad and man. But it’s definitely overwhelming to think realistically about it. Then consider the fact I have another do I get my tubes tied? Hormonal birth control is not an option. How do you even make such a big decision to no longer have babies? 🤯
