Aw, that sounds like a subconjunctival hemorrhage or maybe just prominent blood vessels, which a lot of babies have talaga, pero since your pedia wasn't sure either, I'd really suggest getting a second opinion from another pediatrician or an eye specialist (oftalmologist) para ma-rule out anything serious. A few of us moms had babies with similar red marks and turned out to be nothing, but better safe than sorry with the eyes ng baby, di ba?
