Hi D,
If she is receiving Child Benefit for a child who is under 12 years old, she will earn credits.
These credits will stop the day before the child's 12th birthday.
As long as the credits cover a full tax year, they will grant a qualifying year towards a State Pension.
The birth year and year the child turns 12 may therefore not be a full qualifying year.
If you move out of the UK, we can only keep paying UK Child Benefit if you fulfil specific requirements.
