A teenage carer from Carmarthenshire sat a GCSE exam only hours after getting home from a hospital at 3am following a family emergency, a Senedd committee has heard.

The warning came as witnesses highlighted a “sink-or-swim” reality where children as young as three are taking on caring roles while feeling invisible to schools and social services.

Elektra Thomas, 15, who cares for her autistic, non-verbal brother and her epileptic sister, was part of a remarkable and articulate trio of teenagers who gave evidence to a new health committee inquiry on access to support for unpaid carers on 4 December.

The teenager helps her brother Blake get ready for school in the morning and helps him communicate by acting as his voice, which she has done since about three years old.

Ms Thomas told Senedd members her sister has two children, “so I’m either handling her having a seizure, running around with her medication… or I’m looking after her kids”.

She said: “I’ve been having school assessments at the same time she’s had a seizure.

“I’ve been in ambulances waiting for her to get into a hospital while also studying.”

Ms Thomas explained how she is unable to focus on her schoolwork if her brother has had an overwhelming day.

“I can’t focus on myself and I don’t have time for myself,” she said.

The teenager, who is from Carmarthenshire, described how she was once in hospital until 3am then sat a test – which went towards her GCSE grades – that same day.

Ms Thomas warned young carers do not have time to manage their own mental health, saying: “I didn’t have time for myself, I had time for my brother and sister and that was it.”

She said: “As a young carer who wasn’t noticed for a decade, it was pure manic: I had no coping skills, I had no support – and this has been going on since I was about three or four.”

Albie Sutton, 16, a young carer from north Wales, looks after his disabled mother by doing things such as cleaning the house, budgeting and cooking for the family every day.

Mr Sutton said: “It’s a real struggle for her to move around the house, to even do stuff like getting dressed or moving to the toilet by herself… so I’ve got to help her.”

The teenager estimated his caring role takes up about 25 hours a week and makes it difficult for him to pursue some of his hobbies such as competing in powerlifting.

“My mind feels like a hive of bees,” he said.

“There’s so many things going in and out… I get home at the end of the day and I’m like ‘oh my God, I’ve got to do this, I’ve got to do that’.”

Warning of the mental stress, he added: “It’s also really difficult for me to socialise… I feel very isolated in my caring role, especially at home.

“I’m always housebound, I never get the opportunity even just to go out in my local town.”
