I'm nearly 7 weeks pregnant with DC3, and DH and I are trying to decide when to tell our older children. They're 10 and 7 next month (both April babies) so I suppose a bit bigger than the average age gap. I remember when I was expecting DS2 we didn't tell DS1 until well after the first scan, but then he was only 2 at the time! Does anyone else have experience of telling older children like mine? When did you do it? I'm a bit hesitant about saying anything to them until at least after the scan, but DH is insistent that we tell them before we tell his mother, so now I'm not sure. Help!
