Baby is Home, What Now?

Molly and Bethany address the common question many families wonder about what to do to monitor their HDFN baby once they’re home, and how to know when baby is finally cleared of HDFN. They share their children’s post-discharge monitoring plans, which cover a full spectrum of HDFN severity. If you haven’t already, listen to Season 1 Episode 13 about the neonatal HDFN period. Common terms discussed in this episode:  * Newborn hemolytic anemia * Newborn hyperbilirubinemia  * Hemoglobin/hematocrit * Reticulocytes * Erythropoietin/darbepoetin/ESAs * Thrombocytopenia * Neutropenia * Pediatric hematologist Example transfusion thresholds provided in our Excellent Neonatal Care Practices resource here.

Quick and Nerdy: Iron

Bethany and Molly address iron and its dangers to the HDFN newborn in this quick, science-based episode. Together they address the dangers of iron overload and the confusion around why iron is often mistakenly included in the treatment regimen for newborns experiencing alloimmunized anemia, as well as treatments for extreme conditions.  Watch this episode on YouTube [https://youtu.be/y7ZznU6Sw5M] View all of our resources at www.allohopefoundation.org [http://www.allohopefoundation.org] If you are an alloimmunized mother from any country, you are welcome in our Facebook support group called “Antibodies in Pregnancy: An AHF Support Group.

Quick and Nerdy: Maternal IVIG

In this quick, science-focused episode, Molly and Bethany break down how IVIG (intravenous immunoglobulin) is used during alloimmunized pregnancies to help delay fetal anemia and reduce the risks of severe HDFN. They explain who may benefit, how the treatment works, what the latest guidelines say, and why IVIG can be a life-saving tool when started early and used thoughtfully.
