Postpartum Recovery
Comfort items for the weeks after a vaginal birth. Hospitals send you home with some supplies — ask what yours provides. These ease discomfort; they are not medical treatment.

Frequently asked questions
Which pregnancy products are actually evidence-based?
Very few products have trials behind them. The items here were chosen because a published study, a clinical guideline or a clear clinical rationale supports the category, and each section links its sources so you can read them.
What should I buy first for labour and the first weeks?
Start with the essentials that have the most support: a prenatal vitamin with folic acid and iron, items that make labour more comfortable, postpartum recovery supplies, and a safe sleep setup for the baby.
Are these recommendations medical advice?
No. This page is informational and the research is summarised for a general reader. Discuss individual decisions with your midwife or doctor.
