Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
How often have you seen the children in the last year?
How long on each occasion?
Will she not let you take them out at all?
The law says that children are entitled to regular contact with both parents and the courts can enforce this if necessary.
It is reasonable for you to wish to have the children overnight - and to take them back to Ireland with you during the holidays
The starting point would be for you to have them overnight in the same area as they live - at an hotel - and then for it to move to Ireland after a couple of visits
The starting point is to try and discuss matters with her using Family mediation
However if that fails then you can apply to the court for a Child Arrangement Order - which is likely to be successful in setting up a gradual increase leading to school holidays in your home!
Please ask if you need further details
