A study by Aviva says that stay-at-home dads had risen ten-fold in the last 10 years.
More than a quarter of dads either gave up work or reduced their working hours after the birth of their children, and 44% regularly look after their children while their partner works.
And while many dads seem to relish the time they spend with their children - 43% feel lucky to have this opportunity - financial factors also play their part. When determining who would look after the children, 46% of families said their decision was so the main income earner could keep working.
This is borne out by the growing trend of breadwinner mums. A quarter of women said they earn more than their partner, while a further 16% said they earn roughly the same as their partner.
Louise Colley for Aviva says: "It is interesting to see how the responsibilities of parents are shifting. There is s no longer a norm for who does what in a family relationship, and it is great that many mums and dads are enjoying non-traditional roles. This also means that many families are relying on one salary, which can leave them financially vulnerable. We'd encourage every family to make sure they are financially protected, just in case the unexpected should happen."
