If they are snacks I suppose there is no problem because there are not many places to sit down to eat, except the cafeteria where they have food and drinks.
If you can take food but there is a cafeteria that sells food and the quality is very good. I hope you can go enjoy with your children.
I'm not sure but in the outdoor areas there are cafeterias and also tables with outdoor umbrellas and places to sit so I think there should be no problem bringing small children to eat.
