Lydia says her upbringing was "really tough at times".
"I love my family and they did the best they could but I fell into really dark relationships during my teenage years, so my life got really off track," she explains.
Lydia worked as a full-time carer and says she gave everything to the job and "the other bit of me I gave into my relationships, so I wasn't anyone really".
Feeling a loss of identity after having Casper, Lydia says she became unwell.
"When you have a baby, it really sucks, but you do lose some of your personality – your identity becomes the child because you put everything into them."
'Fru is Casper's godmum'
During her three-month stay at the mental health unit, Lydia was diagnosed with complex post traumatic stress disorder and was recommended to stay with Fru and her family.
She says: "The concept of giving pretty much full rein to another family and not knowing what you're walking into, it's hard.
"Now we come every Sunday for lunch, which is really lovely and we get to spend time with the whole family, because they are my family now – we've been basically adopted without the official things and Fru is also Casper's godmum."
Dorset Council hopes to have at least five parent and child foster carers in the region.
Fru says that to offer this support you "just have to have a spare room and a heart".
"The most important thing it you're authentic, you're quite open about the way you live," she adds.
"I think it's really important you don't over-promise to someone who has difficulties trusting, otherwise you let them down and then you're just in the same category as everyone else who ever let them down."
