I am currently 5 weeks pregnant with baby number 4 and unsure about when to tell my middle daughter who is off to school about the new family edition.I don't want to take the excitement from her about school away by stealing her thunder (my 10 week scan will be around beginning Sept when she starts school) I also don't want to send her off thinking that I have swapped her for a baby-dilema to tell before the school and have it out of the way or let her settle in for a few weeks and then tell her.(I don't think her concept of time is great in that when i do tell her I think that she will think that the baby is coming quite soon)Any great ideas welcome.Thank you.I am not worried about telling the older child or the baby as the eldest has quite a grown up attitude and the baby is still at home with me.It will be the pre-school child that is having the biggest change already to her life.
