Thousands more parents could receive £27 a week by remembering some paperwork shortly after their baby is born.
Child benefit is an allowance that helps with the cost of bringing up children. It is currently worth £27.05 a week for the first child, and £17.90 a week for each subsequent child.
Official data shows that parents of nearly a third of children eligible for child benefit do not make a claim before their baby’s first birthday.
Payments can only be backdated for three months, meaning some families could be missing out on hundreds of pounds in the fog of new parenthood.
The annual publication of the most popular baby names could serve as a reminder to some parents that there are other pieces of official paperwork to complete.

Your bank details

The National Insurance number for you and your partner, if you have one
