Childminder for 4-7th of March in the morning

We are a Spanish family of 5 members: mum, dad, 3 children ( 2 year-old girl, 6 year-old boy and 8 year-old girl). We are going to spend some days in Dublin and we would like that our children have fun by learning English with a childminder in the mornings. This would only apply to the big one children. The person interested in this job should think an activity and spend these morning from 10.30- 12.30 approximately) enjoying with them in places near O'connell bridge. For example: telling tales, paintings and drawing to review knowledge in English and other funny activities for children to learn English.
