My princess was born with hypoplastic left heart syndrome and underwent surgery at 1 week old, having done really well she was released home and within 9 days was back in hospital this time with sepsis!! We nearly lost her but 16 weeks later she was finally home where she belonged, December 6th 2015 maisie was admitted to hospital with a 'cold' to then be told its pneumonia and she'll be ok after a weeks course of antibiotics the care was shocking and she was sent home after 4 days with a follow up from the GP who said she had bronchitis and given antibiotics only January 3rd maisie decided she couldn't fight anymore and sadly passed away in her daddy's arms, he tried and tried to save her but unfortunately maisie was pronounced dead shortly after arriving at the hospital, we then laid her to rest surrounded by her 3 sisters who adored her and the rest of our amazing family we waited for the post mortem to tell us it was maisies heart that had failed, but sadly that was where the story gets worse maisie died of pneumonia which was what she got treated for in December and we was told she was fine, so we decided to see a solicitor to see if we can do anything about it and they told us we have a case we want justice for maisie because we know she'd still be here if they would of listened instead of celebrating her 1st birthday with us we visited a grave we now need help with the costs please please give what you can
