In a couple of weeks we'll be taking my nephews for a day at the zoo - J is 2 and C is almost 1.

I'm assuming I'll need to give them lunch and afternoon tea, we'll have them from about 11:30am til 5pm. Neither of them have allergies, and C still has a couple of bottles a day.

I'm thinking I should pack a couple of sandwiches, a couple of pop tops, some fruit pieces, 2 bottles, a couple of jars of baby food and a few bottles of water, plus whatever Professor and I will eat. Would that be enough? What would you bring?
