How did you know?

Currently my husband and I have 5 kids, we are a blended family but we have full custody of all 5 and treat each child as though they were biological. We have 1 together and have been going back and forth about having one more. I was perfectly fine with being done after the baby was born in 2018 but I can't shake the feeling that we should have another one. I have had dreams about getting positive tests and carrying our youngest daughter and a baby. My husband has also had 3 appointments to get snipped and we canceled them. He is all for having a 6th, he is such a great daddy. How did you know when to be done?
