A leading childcare charity is urging the government to force schools to make term times more co-ordinated.
Schools have their Easter holidays at different times
With this Easter falling so early, different schools' holidays span a four-week period.
The Daycare Trust said the system was costing parents whose children have different Easter holiday times hundreds of pounds extra in childcare costs.
The government said the decision about school holiday dates should be left to local authorities.
Parents with children at different schools are finding that the holidays are longer than usual this year, especially if the schools are in neighbouring local authority areas.
Some schools have already broken up, while others are just closing for a long weekend over Easter with a two-week holiday starting in April.
The Daycare Trust said the government should put pressure on local authorities and schools to standardise term times.
The Local Government Association has estimated that this year parents whose children have different term times will pay an average of £500 extra in childcare costs.
