After school nanny

We have two children who attend different schools which are just around the corner. Our daughter would be required to be picked up at 3:15 and then our son at 3.30. Our son doesn’t require you to go inside, he will meet you at a designated spot. The two kids would require an after school snack and we would love if they sat down and did something creative and educational as they are more likely to do this with someone else. Our 10 year old is very active so going to the local footy oval and letting him run around would help. Ages are 10 and 5. Hours would be 3-7pm
