Breathe 4 Baby: Supporting Asthma Health During Pregnancy and Lactation
The Asthma and Allergy Foundation of America (AAFA) and the American Academy of Allergy, Asthma & Immunology (AAAAI) worked together to create Breathe 4 Baby (B4B). It aims to educate health professionals, patients, and caregivers about the importance of managing asthma during pregnancy.
Uncontrolled asthma during pregnancy may cause negative effects on the pregnancy and fetus. This includes preterm birth, low birth weight, and pre-eclampsia. Keeping asthma well-controlled helps reduce the chance of complications.

Breathe 4 Baby resources include tools to help pregnant and lactating people manage asthma during pregnancy and postpartum stages.
This toolkit was created by the Vaccines and Medications in Pregnancy Surveillance Study Taskforce (VAMPSS), and the Women’s Health in A/I Committee in collaboration with the Asthma and Allergy Foundation of America (AAFA).
