daycare moms who send lunch

So, tomorrow is the big day, I go to work and Joey & Grace go to daycare. Parents provide all lunch and snacks, and I am going crazy with Joey's food. I'm so unsure what is enough and appropriate to send. They have a microwave and fridge in the classroom. He is 17 months old, what do you think?

in his lunchbox I packed-
mashed potatoes and cut up chicken cutlet from dinner tonight
a container of yo baby yogurt
fresh cut up melon
some baby goldfish in a ziploc bag
2 sippy cups- one with milk, one with water

Snacks- I am sending in a gallon size ziploc filled with individual applesauce containers, goldfish, pretzels, animal crackers, veggie sticks, etc. and i'll have them tell me when it needs to be refilled.
Sound good? Too much food? not enough?

I usually always sent leftovers, and sometimes chick nuggets or fishsticks.
I think what you have sounds great
