Explaining to your other children about a new baby

Alexandra
How did you tell your young ones there would be a new baby coming into the house. I'm only 6 weeks I know it's really early. But I have a 2.5 year old and I am very concerned she is not going to be happy with a new baby. She already is a big suck to me she just loves the attention. She also doesn't talk much she's got a vocabulary of maybe 5 words. She doesn't listen very well. She's not bad or anything just like when I call her name or ask her to out her toys away she ignores me. I'm just worried it won't go well and she will be upset.
