Tomas is babysitting his neighbor’s seven-month-old child who has just begun to eat solid foods. the parents did not mention any food allergies, but tomas would rather be safe than sorry. which food is the safest option for tomas to offer the baby if he wants to minimize any potential problems with food allergies?

The safest kinds of foods Tomas could give to the baby are infant cereal that is made with his mother's breast milk or if the baby is not breastfed then with the formula milk that they are given, never cow's milk. He could also try to give the baby pureed foods that consiste of only one item and no seasonings in it at all. 

What are the choices?
