Lost memories...

I'm in the process of transferring old home videos onto dvd. I was doing quite well until I started looking for the video made of the day Matthew was born - him under the heat lamp coz he couldn't keep his temperature; his clothes on the radiator in the ward coz he'd been sick down them, nana and grandads first cuddle... then later of Matthew in the garden laughing at Darryl, the very first time he laughed, and it was amazing, he laughed so hard it was SO funny... and it was also of his first few weeks at home, and down by Godmanchester locks.... but I can't find it. I've looked everywhere and it's nowhere to be found...
