Catrin is a teacher who's on maternity leave looking after her daughter Llinos
She finds it a little difficult to get people to baby-sit.
However, she does manage to go shopping and regularly helps out in the primary school.
She often talks to her cousin about the health of Guto's father and her argument with Guto over whether they should buy a new car or a new kitchen.
Life is a balancing act for Catrin in this family!
