Ideally you want to wait until 6 months to start solids to avoid any possibility of allergies to foods. It's really important to feed your baby right from the start because this is the time when they are forming the cells that will be with them for life. There is a connection between diet and disease. It is well documented in The China Study by T. Colin Campbell (Cornell Professor and Researcher).
If you want to follow a more holistic feeding schedule, I recommend the following:
6-8 months
Water in a sippy cup
Avocado, Bananas, Peaches mashed
Cooked vegetables, mashed, such as sweet potatoes, carrots, winter squash and peas
Gluten free grains like brown rice, millet, quinoa (great source of protein!) and buckwheat mushed and thinned with breastmilk
Tofu, soy milk, and soy yogurt
8-10 months
Baked and mashed potatoes thinned with breast milk
Well cooked legumes- pinto beans, lima beans, kidney beans, split peas
Fruit juices except citrus (best made at home with a juicer and watered down)
Soft crackers made with whole grains
10-12 months
Citrus juices and fruits
Thinned nut butters
Pasta chopped small
Whole-grain bread
Gluten grains such as oats, rye and barley
Corn
Other Soy products
Ground nuts and seeds
Organic poultry and meat (not necessary, but if you choose to give baby meat, make it organic)
1 year and older
Organic Free Range Eggs (optional)
Honey (optional)
Fish (optional)
I also highly recommend the book "Disease Proof Your Child" by Dr. Joel Fuhrman. This is a must read for all new moms who want to understand nutrition and start their kids of right from the start.
