Hi Claire, firstly congratulations!!! I think its is wonderful tat you are looking for ways to deal with any "problems" that may arise with the discovery that you are pregnant.

I have three children, my eldest two being DH's steps... We didn't tell the kids until I was about 10weeks pregnant, my daughter figured it out... she's a bit like that. My son just wanted to know if it was going to be a boy! lol

As it got closer to Aston arriving my daughter started to get distressed about the fact that they wouldnt have the same dad, and that he was only going to be her "half" brother. I said to her, that really Aston was only half related to all of us... me and DH too, and that when he was born we would have a look to see which "half" was connected to her. I said to her, that it didn't matter that they didn't have the same dad, it was going to be her brother regardless. She smiled, and seemed to settle. When Aston arrived, Nathan was the first out of them to hold him, he was overwhelmed with emotion, and still is actually. Laura didn't want to hold him, she was frightened that she wouldnt hold him right. I just whispered in her ear that this was the only time he was going to be brand new, and that she might regret not having a cuddle with him later. So she sat down, and I watched a display of emotions run over her face as she fell inlove with him. As she left, she lent over to give me a cuddle, and said to me "youre right mum, it doesnt matter". they are both so incredibly in love with him. I wondered if the novelty would wear off, but it hasn't. Today they sat and played with him with playdough and goop, and enjoyed it as much as he did. My favourite thing in the world is to listen to them play with Aston, and Aston laugh with delight.
