6 months
In general follow the guidelines for pregnant women on the number of servings based on the mercury level of the fish BUT use a baby size serving ( 0.5-1 oz before age one, 1oz from age one to two, 1-2oz until age 4, etc)

First foods for babies
Meat and fish
Babies often prefer well-cooked chicken, which is soft and easy to eat when shredded. Be careful to remove even the tiny bones when serving fish.

Yet experts say children over 6 months can handle most anything, with a few caveats: Be cautious if you have a family history of allergies; introduce one food at a time and watch for any problems; and make sure the food isn't a choking hazard.
Parents elsewhere in the world certainly take a more freewheeling approach, often starting babies on heartier, more flavorful fare — from meats in African countries to fish and radishes in Japan and artichokes and tomatoes in France.
The difference is cultural, not scientific, says Dr. Jatinder Bhatia, a member of the American Academy of Pediatrics' nutrition committee who says the American approach suffers from a Western bias that fails to reflect the nation's ethnic diversity.

Egg yolks, rich in choline, cholesterol and other brain-nourishing substances, can be added to your baby's diet as early as four months,1 as long as baby takes it easily. (If baby reacts poorly to egg yolk at that age, discontinue and try again one month later.) Cholesterol is vital for the insulation of the nerves in the brain and the entire central nervous system. It helps with fat digestion by increasing the formation of bile acids and is necessary for the production of many hormones. Since the brain is so dependent on cholesterol, it is especially vital during this time when brain growth is in hyper-speed.25 Choline is another critical nutrient for brain development. The traditional practice of feeding egg yolks early is confirmed by current research. A study published in the June 2002 issue of the American Journal of Clinical Nutrition compared the nutritional effects of feeding weaning infants 6-12 months of age regular egg yolks, enriched egg yolks, and an otherwise normal diet. The researchers found that both breastfed and formula-fed infants who consumed the egg yolks had improved iron levels when compared with the infants who did not. In addition, those infants who got the egg yolks enriched with extra fatty acids had 30 percent to 40 percent greater DHA levels than those fed regular egg yolks. No significant effect on blood cholesterol levels was seen.26
Thus, the best choice for baby is yolks from pasture-fed hens raised on flax meal, fish meal, or insects since they will contain higher levels of DHA. Why just the yolk? The white is the portion that most often causes allergic reactions, so wait to give egg whites until after your child turns one.1,11
