Postpartum & Newborn Tools & Calculators
21 free, private tools grounded in ACOG, AAP, and CDC guidance — for your fourth-trimester recovery and your newborn's first weeks. Every one runs entirely in your browser: nothing you enter is sent, saved, or shared.
Postpartum recovery
Recovering after birth
Bleeding, mood, and fertility after delivery — with the warning signs that never wait.
Postpartum Recovery
How long since the birth? See what's typical at your stage — bleeding, mood, healing after a vaginal or cesarean birth — plus the warning signs that mean call your provider or 911.
Open toolPostpartum Depression Screener
The full Edinburgh Postnatal Depression Scale (EPDS), scored privately on your device with the published cut-offs — for pregnancy and postpartum, with crisis support built in.
Open toolPostpartum Psychosis Checker
Rare but a true psychiatric emergency, usually in the first two weeks after birth — hallucinations, strange fixed beliefs, no need for sleep, confusion. Written for the parent and the worried partner alike; any sign means act today. Not a diagnosis.
Open toolBreastfeeding Birth Control Check
Answer the three WHO/Bellagio criteria and see whether breastfeeding is protecting you from pregnancy today — about 98% when all three hold. Plus your exact expiry deadline, and what to start before it flips.
Open toolBirth Control After Birth
Three questions — time since delivery, breastfeeding, clot-risk factors — and see the earliest safe start for every method, from the implant and IUD to the estrogen pill, per CDC guidance. Private, runs in your browser.
Open toolDiastasis Recti Self-Check
Walk through the postpartum finger-width test for abdominal separation, then get a plain-language read on the gap you feel — about a finger or less is typical, and most narrows on its own. Private, not a diagnosis.
Open toolMastitis vs Clogged Duct
A red, warm, painful wedge of the breast while breastfeeding — see whether it fits a plugged duct (no fever) or mastitis (fever, flu-like), the safe first steps, and the red flags that need a clinician now. Not a diagnosis.
Open toolPostpartum Thyroiditis Checker
The thyroid shift that can follow birth — an overactive then underactive phase, easy to mistake for exhaustion or mood changes. See whether your symptoms fit and whether a simple thyroid blood test is worth asking for. Not a diagnosis.
Open toolPostpartum Preeclampsia Checker
High blood pressure can appear in the days to six weeks after birth — many don't know it. See which warning signs mean call your OB now, which mean 911, and why they are not normal recovery. Not a diagnosis.
Open toolPostpartum Bleeding Checker
See whether your bleeding fits normal lochia for how many days postpartum you are — and spot the warning signs of postpartum hemorrhage or infection that mean call your provider or go to the ER now. Private, in your browser.
Open toolNewborn care
Caring for your newborn
Feeding, jaundice, fever, and the everyday worries of the first weeks — leading with the danger signs, never a diagnosis.
Newborn Jaundice Checker
Walk through your baby's age, how far the yellow reaches, feeding and wet diapers, and risk factors to see whether to simply mention it or get seen urgently — with the emergency signs first. Not a diagnosis.
Open toolNewborn Fever Checker
Enter your baby's age and temperature to see how urgently a fever needs care — anchored on the rule that 100.4°F (38°C) or higher in a baby under 3 months is a medical emergency. Leads with the danger signs. Not a diagnosis.
Open toolNewborn Weight Loss
Enter birth weight and current weight (grams, kg, or lb-oz) to see what percent your baby has lost — with a plain read on whether it's typical, worth a feeding check, or a reason to be seen. In your browser, never a diagnosis.
Open toolBaby Feeding Amount
Estimate how much formula a healthy, full-term baby needs — about 2.5 oz per pound of body weight a day, split into age-typical feeds — as a sanity check, not a target. Breastfed babies feed on demand.
Open toolBreast Milk Storage
How long does expressed milk keep? Pick freshly pumped or thawed and where it's stored for the CDC keep-time, then add your pump time to get the use-by date. Private and in your browser.
Open toolColic Checker
Hours of crying in a healthy baby has a shape — the rule of threes, a 6-week peak, an end by 3–4 months. Check the fit after clearing the medical red flags first, with the put-the-baby-down-safely message said out loud. Not a diagnosis.
Open toolBaby Reflux Checker
Happy spitter, GERD, or an emergency? Sort effortless spit-up from the vomiting patterns that need care now — projectile, green, or bloody — with weight gain and feeding comfort as the tiebreakers. Not a diagnosis.
Open toolNewborn Rash Checker
Most newborn rashes are harmless — blotchy erythema toxicum, milia, baby acne. Check yours against the glass test and the danger signs: non-blanching spots, early-weeks blisters, or any rash with fever mean care now. Not a diagnosis.
Open toolIs My Newborn Getting Enough?
The question that haunts the early weeks, answered by the objective evidence: wet and dirty diapers, feeding frequency, and the weight trend, not how full baby seems. Leads with the dehydration danger signs. Not a diagnosis.
Open toolBaby Stool Color Checker
Baby poop comes in alarming colors, and most are normal. Sort the harmless yellows, greens and browns from the three that mean call your doctor — white/pale, black, and red. No photos, leads with the urgent signs. Not a diagnosis.
Open toolSafe Sleep Checklist
An AAP-based safe-sleep checklist to lower the risk of SIDS and sleep-related infant death. Tick what's in place and see the highest-impact fixes — Alone, on the Back, in a bare Crib. Preventive, private.
Open toolWhy trust these
Built to a clinical standard
Each tool is a transparent rules engine built directly on published guidance, chiefly ACOG, the American Academy of Pediatrics, and the CDC, not a black box.
Every result is framed as an estimate with a clear next step, never as a diagnosis, and every tool links to the exact sources it uses and the date it was last reviewed. Because they run on your device, using them tells us nothing about you.
