My daughter's daycare had a holiday gathering and each family was asked for bring in something from a list for everyone. Parents were invited.
The parents were not allowed to partake in the food and just had to sit there while their child and daycare workers ate. We brought in enough for everyone (that included the other parents!!) and saw everyone else did the same by the amount of snacks in each bag/box.
Would you find this strange? We were not even offered water.
