New research has found the cost of childcare in the East of England has risen nearly three times faster than wages in the last decade.
The Trades Union Congress (TUC) says the amount parents are paying has gone up 35% since 2008.
They are now calling for subsidised, affordable childcare to start when maternity leave finishes.
But the government says it is already investing a record amount in childcare - which will reach £6 billion a year by 2020.
