The first step in producing tasty, nutritious food for your baby is to select fresh, good quality produce.  Buy organic if possible, and make sure fruits and vegetables are ripe and blemish-free. Try to use or cook all foods within 2 or 3 days after purchase. Choose items like apples, pears, peaches and sweet potatoes to try first.  Avoid foods that may be stringy or hard for baby to swallow, such as green beans or peas with shells, unless you pass them through a fine strainer after they have been cooked and blended.

Vegetables, meat and grains on the other hand, will need to be cooked first. You have several options when it comes to cooking methods:  Steaming is the best option when it comes to cooking vegetables, as it preserves the most nutrients. Use a steamer basket, or simply place a colander over a boiling saucepan of water. Steam produce until it is tender, usually about 10 to 15 minutes. Boiling can be used to cook grains, vegetables and certain animal produce. You can boil the food in a broth to add more flavor, if you wish. Baking is a good option for things like sweet potatoes, cruciferous veggies, meat and poultry. You can add a little flavor to these items by adding herbs and mild spices during baking (don't be...
