These women were proficient in dealing with difficulties arising during pregnancy and labour but as most of the information we have about their practices is passed on from upper class Aztec men and the Spanish conquerors, much of the traditional knowledge has been lost. A tlamatlquiticitl attended every pregnant woman, no matter status or class, although women of higher status often had more than one attend them. The tlamatlquiticitl was essential to assisting in birth, and additionally to providing prenatal care advice. The Florentine Codex outlines much of the advice the tlamatlquiticitl gave to expecting mothers. The mother was advised to engage in sex with her husband during the first few months of the pregnancy so as to help the child develop, but around the seventh or eighth month she was to abstain. If she did not it was believed that the semen may act like glue and the baby would not come out, or if it did it would be feeble with misshaped fingers and toes and covered in what looks like atole so that everyone would see how the couple could not abstain, and they would be shamed. The expecting mother was also told she must avoid prolonged periods in the sweat bath, for too much heat was thought to roast the child and it would be stuck inside the womb; however, too much heat specifically around the abdomen area would cause the child to swell and suffer from the heat. Chewing chicle was not allowed otherwise the baby would be born with perforated lips and would not be able to suckle or eat. Likewise if she ate earth or chalk the child would be in poor health. The tlamatlquiticitl knew that the baby took nourishment from the mother and so what she ate it would absorb; if she fasted the child would starve. Because of this the mother was to eat and drink well, even after the birth. The mother was also warned not to look at anything red otherwise the child would extend crosswise, making for a complicated delivery. She was not allowed to observe lunar eclipses, otherwise the child would be born with a cleft palate. Eclipses were also associated with miscarriages. And she was also not to look at anything that would frighten or anger her lest she should harm the child. Walking around late at night was avoided otherwise the child would cry incessantly. If the mother took naps during the day the tlamatlquiticitl warned that the child would be born with unusually large eyelids. Lifting heavy objects was also associated with damaging the fetus.
