This is the Irish language version of 'A Fairy in the Family'. As you can se our translator made changes where he saw fit and this title means a fairy in the house.
The story is exactly the same. Beici has been up to some well-meaning bold spells and it has been ruining her costume. Gaelscoil children as young as five like this one but I think eight is a good age for non-Gaelscoil children to try this on their own.
