[Lighthearted]
Currently at a family gathering on the Husbands side, and his lovely but slightly strange aunt has just shared this advice with me.
Aunt - Is your DD jealous that you're pregnant and having a new baby?
Me - No, she's really excited. She loves talking to my stomach and watching her brother wriggle when he hears her voice.
Aunt - That's not good KungFu. You want her being jealous!
Me - I do? 
Aunt Of course you do! It's well known siblings get on better when there is jealousy and competition. Don't let DD near the new baby for a while or join in and trust me they will have the best bond in later life.
Just look at my two!
She then pats my hands, with a big smile and walks off. Happy with herself for sharing her wisdom.
As a side note her two, do not get along at all. You could place them in an empty room, and they could get into a fight.
Anybody else have any crazy advice that was given them?
