WHY!!!!!

I was just lookin for some advice. I am not sure if anyone has had a situation anywhere close to this one but here goes. I had three children by the time I was 19 and a miscarriage.By the time number three came along me and my husband were in serious financial trouble and decided a vasedtomy was the only way. Now six years later we want more children and are having it reversed. The problem is I am scared to tell my mother in law and his brothers. I am terrified that they will think we are crazy. I am scared they will think we are not able to care for more children even though we are, They think we are dirt poor because we hit a hard spot last month. We are financially secure and have built our saving back we just had an unexpected expense come up. It happens. I am wondering though if we should just have it done and not tell them , just let them think the vasectomy came undone or tell them. I love my inlaws just as much as my blood family if not more.They have always been there for me no matter what. I don’t want them to be upset with me. What should I do?:unsure:
