Certain batches of powdered Similac were recalled in September due to possible contamination with beetle larvae. After testing recalled batches, Similac found nearly 99% of product was not contaminated. And I know it sounds gross, but ingesting beetle larvae will not actually harm a baby. However, I do agree with Happynifer; if you can get a lactation consultant, sticking with breast milk is ideal. Otherwise, the formula you buy now should be fine (providing you did not buy this back in September). Good luck!
go find a lactation consulant or la leche league leader in your area.
99% of breastfeeding issues are due to an improper latch. they can probably fix your problem pretty quickly. then you don't have to worry about the formula issues at all.
formula scares me. too many problems with obesity, colic, metabolic issues like diabetes down the road.....and that is in formula that isn't contaminated.
