I am not asking you, the reader, this question... this is actually a question I have been asked several times over the last few years. Why? Because we want more than two children!! Seriously, that is why some people ask us this question.
I was having a coversation with a mom who is my age (with children who are 3 & 1) a few months ago and she actually just came right out and said "so, does that mean you're a mormon?" We were discussing children and how Michael and I wanted more (this was before I got pregnant with the one I'm currently carrying) and that's how the conversation went.
I know it's well known that, in general, Mormons (along with a few other 'religions/denominations') typically have several children. I'm not sure if it's because they don't believe in birth control, or if they simply allow God to bless them with however many children he chooses, or for some other reason.
I don't really know a lot about very many other 'cultures', so I can't tell you what it's like in other countries, but I think there is some unspoken rule in this country that you are NOT suppose to want more than two kids. If it happens, oops, but you can never actually plan to have more than that. In my opinion, this is a terrible way of thinking. I believe God created us to "be fruitful and multiply" and following His will is #1. Trusting in God is the only way to do anything. This includes the number of children you have. God should determine that - not society, family trends, finances, etc. I belive if you truly trust God and put all things at His feet, the rest will fall into place (not to say that doesn't take a tremendous amount of faith, obedience and going-against-the-world, but isn't that what God commands anyway?)
This is not to say that I'm judging those who have decided to stop at one or two children, because that would be wrong of me. I just wish more people would prayerfully consider what God really wants for their lives and truly let God lead them in the proper direction (not just in this, but in all things).
How many children will we have? I honestly don't know. God has not given us a number. We take it one at a time and if we feel that God is leading us to have another after this one, then we will definitely do so.
PS - I only have 2 siblings, but Michael has SIX. His parents were divorced when he was very young (around 2) and they both remarried when he was also young. His mom went on to have one more child (I'm not sure of circumstances, this may have been a medical decision....because she has many times mentioned how she would have liked to have had more) and his dad went on to have FIVE more children. Michael's dad is also one of FIVE and 4 of those 5 children all have more than 2 children of their own.
