There are twice as many children waiting for adoption, as there are potential parents willing to adopt.
Now, Banbury-based charity, Adoption UK, is campaigning for more prospective parents to consider the option.
The number of children waiting for adoption from black, Asian, and minority ethnic (BAME) backgrounds is disproportionately high.
Alison adopted a five-year-old girl, after realising that having children herself was not an option.
She says, despite the challenges, she's been proud to have her as her daughter, who's now a teenager.
The charity is being supported by Olympic Gold medallist and adoptive parent Tessa Sanderson.
She is an ambassador for the charity, and over the years, has been keen to promote adoption.
