Hi, I just found this site yesterday, and read your post today. I joined and wanted to give you a few words.
I am 26yrs old and the happy mother of four children ages 4,3,2 and 8mon. Yea, that's right. When we found out we were pregnant with our third child, we were nervous about telling family as well. I can still remember worrying about it so much, but when we did spill the beans, everyone was supportive and happy. My Mom did have some concerns, but I laid her fears to rest. We used the pull out method, too. You can tell how effective it has been for us.

Hope this helps.
