I'm not sure if this is the most sufficient place to post this but it seemed about right..
My little girl was born on the 7th. The first full day that we had her home we noticed a tiny spot of blood in her wet diaper. We called the pediatrician and she said it was perfectly normal for a new born to be affected by a mother's hormones and have a small period. Well we just finished day 2 and there have been a couple spots of blood here and there. I am wondering how common this is and about how long it will last? It kind of freaks me out to see blood in my little one's diaper! Also I feel a little guilty like I am having a negative affect on my baby.
Both my DD's had this. It is a little disconcerting to see any kind of blood in a newborn's diaper, but really, like the PP said, totally normal and not at all your fault. Think about the amazing and crazy things our hormones did to our bodies while we were pregnant. It is natural that they would have some withdrawing from those hormones to do when they come into the world. My new DD was born on the 3rd and I think her "mini period" just ended. It probably started day three, so that would be about 5 days. It can last longer, but as long as it is just streaks and spots, I think it is totally fine. I must admit, it distressed me a bit too, even though I saw it with my now 6 year old. Remember, we are withdrawing from hormones too, which can make us emotional.
