My son is 5 and will be almost 6 when he gets his first brother or sister in April next year. I am wondering when to tell him. He has a brain of a 2 and a half year old in most areas but excels in maths, science etc. I don't want to tell him to early so he's waiting for ages, yet I don't want to tell him to late so he doesn't have time to adjust. I think he'll be fine with a new baby as he quite likes them and I honestly think if I just bring it back from the hospital he'd be ok with it. He's a very placid boy and adapts easily, but I want to make it somewhat special for him also.
