Re: Magical urge to eat at 12 months??
My son didn't eat solids on any regular basis -- ie, not everyday, and never more than about a tablespoon of food on the days he did eat -- until he was 2 years old. He breastfed like a newborn, about every 1-3 hours, with occasional 4 hour breaks. Although his weight dropped off quite a bit at about 18 months, it did not become a major issue, and even though his nutrition was coming almost exclusively from breastmilk for those two years, he never showed obvious signs of nutritional imbalance.
Some babies have a really hard time eating solids through teething, and for those for whom teething lasts a long time, that can delay the inclination to eat solids for quite awhile. Personally, I wouldn't worry about it unless an actual medical problem seems to be resulting from the lack of solids.
If you are interested, there are also some great techniques in Chinese Medicine for stimulating appetite in children, so if it's accessible to you, you might consult with a Chinese Medicine Practitioner (preferably one who specializes in pediatrics).
Don't let people scare you into worrying about a problem that may never actually come to pass...
