I am wondering if anyone with a preemie has used an alternative to polyvisol for a multivitamin? I just purchased some Rainbow Light "NutriStart" powder. I don't like the idea of giving dd a synthetic and artificial product like polyvisol. DD was born at 32 weeks, is 38 weeks now and the powder I bought has dosage for 6-12 month old. I was thinking of just halving the dose?
