How long can a 2 1/2 year old safely go without food? Weird question, I know. Please just answer with facts.
Your child needs to grow. Feed children no less than 2 meals a day every day. If possible give them vitamins too. Children aren't an experiment. http://feedingamerica.org/hunger-in-america/hunger-facts/child-hunger-facts.aspx#
Feed the child!!!!!
I hope this is an experiment on paper only.
A child should eat and drink every four hours
