My DD is 4.5yrs, and REALLY looking forward to having a little sibling. She's also not quite able to understand the concept of time; still asking when her birthday will be here and that not for 6 months. Also she doesn't understand the concept of keeping it a surprise from her grandparents until much later when we're far enough along to tell the rest of the family. At what point in your pregnancy did you or are you planning on telling your other children?
Also, I'm looking for cute ways to tell her. Thought of getting her the big sister shirt and a book. Other ideas? What did you do, or are planning on doing?
