In nine months there will be a new addition to your family. Your only child has not had to share you or anything else before. Once you know you are about to add a new addition to the family whether it s through birth or adoption, you should let your child know as soon as possible. Don t wait until right before things are going to happen before you tell them the news.
Children are like anyone else, they don t like surprises.
If you keep it a secret they will feel like something is wrong and will automatically have negative feelings about the situation. Talk to them about how all of you will become one big happy family and you will be there for them and the new member also. They needed to feel as much as involved as they possible can. Let them help in decorating the new room and getting ready for them. Make them feel they are a part of things and not being sat aside because someone new is joining the family.
