I need advise?

OK, I'm an active member of the LDS church (Mormon), so I can tell you what I would tell your mother in law, and this is EXACTLY what the church preaches. Tell her that President Hinckley himself said that the decision of how many children to have, and when to have them, is a decision that is made between the couple themselves, and their Father in Heaven. Mother in laws DON'T factor into the equation. I'll find a link for you after I post this. Here's the link: http://lds.org/ldsorg/v/index.jsp?vgnextoid=bbd508...

And here's what it says: Children are one of the greatest blessings in life, and their birth into loving and nurturing families is central to God’s purposes for humanity. When husband and wife are physically able, they have the privilege and responsibility to bring children into the world and to nurture them. The decision of how many children to have and when to have them is a private matter for the husband and wife.

I'd also point out to her that the LDS church frowns VERY heavily on premarital sex, so if you got pregnant before you married her son, her friends at church would NOT think highly of that at all.

Those 2 ought to shut her up.

If mom is a Mormon, she is very unorthodox. Mormons believe family should come after marriage. Also, Mormons believe each couple should decide when and how many children they wish to have, free of pressure from the outside.

You could tell her that while it's sweet of her to be so enthusiastic about your having children together, you both would like to settle in as a married couple for a few years first. Congrats on your engagement!!!!

tell granny when god graces us with our bundle of joy she will be the first to know.but lets get through the wedding first,and so on...

I'm afraid there's no escape. You'll just have to grin and bear it. And bear it. And bear it.

next time she mentions it, ignore her...don't respond at all....if she doesn't get the message,you need to talk to her about it.
