DH and I were thinking of keeping our big news private until at least the 10 week mark, but we're finding it a bit hard to keep the news from his parents. We live with DH's parents, and my MIL insists on doing all the cooking, but she doesn't know I'm pregnant and can't eat (or can't keep down) certain foods she makes. They are going to be thrilled by the news, but I just don't want to get their hopes up. I'm so early in this pregnancy and anything can happen. My MIL would be devastated if we lost the baby. But, it's quite hard to keep it a secret when I turn green at the dinner table. Should I just tell them the news and explain to them that it's very early?
