The twins who are 'one in a million'

From the outset I wanted to make sure we had as normal a family as possible for everyone's sake.

But as soon as we got Sean home it was extremely apparent that he was very different to his sister.

As they were exactly the same age, it made his Down's even more obvious.

If you just have one child with the condition you don't have another one to constantly compare them to, and I'll admit it was very hard to watch Lisa rapidly grow and develop while Sean lagged so far behind.

She was bright and alert, while Sean was floppy and not nearly so aware of his surroundings.

Regardless of Sean's disability, to me they will always be two little peas in a pod - and that's just the way they think of it, too.
