Is that plain rice or rice products marketed for babies such as rice cereal?
My children never ate that stuff, they just had real rice when they were ready for it and not all the time.

Eating Rice Products Exposes Infants to Arsenic
By Cara Adler
Infants who eat foods containing rice have higher urinary levels of arsenic than infants who eat no rice, according to a New Hampshire birth cohort study in Pediatrics. (Prior studies suggest that exposure to arsenic early in life may have adverse developmental effects.)
Among over 700 infants whose parents completed dietary interviews, 80% started eating rice cereal within the first year. Researchers collected urine samples at age 12 months from 129 infants, of whom roughly half had eaten rice or rice products (e.g., puffed rice snacks) within the prior 2 days. Total urinary arsenic concentrations were significantly higher in the infants who had eaten rice or rice products than in those who had not.
Dr. F. Bruder Stapleton of NEJM Journal Watch Pediatrics and Adolescent Medicine concludes: "This study shows an association between urinary arsenic concentrations and ingestion of rice products. While not proving causation, the results support the FDA recommendations for infants: don't provide rice as the sole grain and use rice products in moderation."
