In an exclusive interview, we've been hearing from the mum of a four year old girl from Reading who's getting ready for surgery in Bristol which could change her life.
Four year old Harper Exell, who has Spastic Diplegic Cerebral Palsy, is due to have a major life-changing operation at Bristol Children's Hospital in February next year.
The NHS is paying for that, but Harper's family need £15,000 to ensure she can then be given rehabilitation care and support afterwards.
Harper's mum Paige is leading the campaign to help her daughter - she's told us it's vital her child is able to receive the treatment she needs:
"We want to help Harper have her chance of being able to walk on her own, independently.
"We want her to be able to live to the full in the future.
"Any donations will go towards her recovery.
"All she wants to do is to be able to walk around like her brothers and sisters - and live her life to the full."
Paige has told us she's so incredibly grateful for the support specialists in Bristol have already given Harper and the family.
She says there are a number of challenges they'll be facing, but they're all ready for them:
"Initially Harper has three weeks in the hospital there when she has the operation.
"When we get home, the NHS physiotherapy slowly reduces over time.
"We've had a couple of appointments there at the moment - and it's given them an idea of what the operation itself might be able to achieve for her.
"After that, it's our job to try and maintain as much private physiotherapy as we can."
