Keeping the gender a secret?

I'm still TTC, but I have decided that when I do get pregnant, I want my husband and I to know the gender of the baby and then everyone else will find out when they visit us in the hospital.

I have a few reasons for this. When it comes time for the baby shower, people like to focus on the cute clothes and other gender specific items, but I know we would need help with all the larger, more expensive items. I can easily get clothes. I figure, if no one knows the gender, they will be more likely to work off the registry of things we actually need help with and it will be easier to ensure the larger items stay gender neutral so we can use them for future children as well. I also just like the idea of it being our secret. We are the only ones who made the baby, we should be able to have something that is kept to ourselves for a little while.

The problem is, I am almost certain my husband won't go for it. Our families would, of course, constantly be trying to get us to tell them, and with how close he is with his mom, I don't know that he could keep the secret.

I know we still have plenty of time before we have ti worry about this, and who knows maybe I will change my mind when the time comes, but these are the type of things I like to think about and "plan" while TTC.
