Thanks for posting your query at HealthCareMagic. Ideally (as per American Academy of Pediatrics as well as World Health Organisation) a two month old baby should be exclusively breast fed for 6 months after which weaning with semi solid food like mashed boiled food or cereal based formula is done. I would not recommend introduction of rice at this age though many baby food companies market their stage 1 foods to children between 4 and 6 months old with the precaution that the food is meant to be consumed in addition to breast milk or formula. So, try switching back to breast milk if adequate amount can be procured. In case of an working mother, breast milk can be expressed and stored in a refrigerator. If not, formula feeds including similac alimentum may be given. It is hypoallergenic. I do not know if your baby has milk allergy or a similar condition due to which the pediatrician asked him to take such a formula in addition to rice. It is not likely to cause paleness during sleep. The paleness can be evaluated by checking the hemoglobin content of blood. Hope that would resolve your queries. Feel free to revert back in case of any further queries.
