My dd was born at 23 weeks and weighed 1lb 2. You could see through her skin.
She was ventilated and on shedloads of steroids and was fed tiny quantities of my milk through a tube into her tummy. I had to ask permission to touch her. She had blood taken from her heel every few hours to check her lungs were working properly; after a couple of weeks the skin on her feet was completely broken down like a wound that never healed.
She's had a heart operation and an eye operation. She's had whooping cough and chicken pox.
Today's her second birthday. She's not on oxygen or any medicine any more. She's running and talking and giggling, and smashing all her developmental milestones. I sneezed this morning and she said 'bless you, Mummy'.
I'm the proudest mum in the world.
