On April 26th 2000, my beautiful and perfect first born baby Maisy died unexpectedly and suddenly in the night. She was just 10 weeks old. Maisy had died of sudden infant death syndrome.

I can't think of any pain worse than losing your baby. The ache of empty arms, and the loss of her smile and her touch is unbearable. Unspeakable.

As a family we have always celebrated Maisy's birthday and on the anniversary of her death, I struggle through what is always the worst day of my year. This year, on what will be the 26th anniversary of Maisy's death I am going to attempt to run the London Marathon to raise money for the Lullaby Trust.

The Lullaby Trust is a charity that saves babies' lives and supports bereaved families. Around 3 babies a week still die from sudden infant death syndrome (SIDS), The Lullaby Trust is committed to bringing that number down to zero.

Maisy's life and death changed my life immeasurably. I think about her - and what sort of person she would have grown up to be. I was lucky enough to go on and have 3 wonderful children, but nothing will ever replace her. She will always be my first born child. My beautiful little girl. I am grateful for every hour of the 10 weeks we shared. She made me the mother I am now. And she taught me how to appreciate every single moment of every day.

I will be raising awareness and funds that will be helping grieving families to receive specialist help, funding research to prevent more babies from dying suddenly and unexpectedly, and allowing more parents to receive advice on safer baby sleep.
