The "childcare crunch" is also affecting families with school-age children, as suitable after class childcare becomes more expensive or is cut by the local council, Labour will say.
In a speech on the rising costs of childcare and squeeze on wages, Mr Miliband will say:
This childcare crunch is affecting families with kids at school too. Parents are facing a daily obstacle course as they seek to balance work and family life.
Under the last government 99% of schools provided access to breakfast clubs and after-school clubs.
But more than a third of local authorities have reported this has been scaled back in their area under David Cameron.
The Tories say they care about families but they have done nothing to help for three years while all the time adding to the stress and strain of family life.
