Kick Counting With Twins: Why Per-Baby Counts Don't Work
Counting each twin separately sounds more careful, but maternal perception cannot reliably tell twins apart, and one baby's movement can push the other. Here is what to track instead, when to start, and why reduced movement is still an immediate call.
Newborn Feeding Schedule: Breast, Formula and Combo (Weeks 0–12)
A healthy newborn feeds 8 to 12 times every 24 hours — the same band for breast and formula — but the gaps stretch with age and collapse entirely at 7pm. Here is what the guidelines actually say, week by week, and how to tell your baby is getting enough without weighing them daily.
Normal Kick Count Patterns: How Many Kicks Should You Feel?
Guidelines are clear that there is no set number of movements that counts as normal. Here is when kicks start, when a real pattern forms, how the count-to-10 method actually works, and why reduced movement is an immediate phone call, day or night, rather than a wait-and-see.
Ovulation 101: When You Are Actually Fertile
Your fertile days are a six-day window that closes on the day you ovulate. Here is where those days fall, how cycle length moves them, and what cervical mucus, LH tests and basal body temperature each actually tell you.
Postpartum Recovery Timeline: What to Expect Week by Week
Recovery after birth is not a straight line, but it does have a shape. Here is what usually happens in week 1, weeks 2 to 4, at the six-week check and in the months after — including how a C-section changes the arc and the red flags that are a same-day phone call.
Pregnancy Weight Gain: How Much Is Right for You (IOM Targets by BMI)
There is no single right number for pregnancy weight gain — there are four, and the one that applies to you depends on your BMI before you conceived. Here are the IOM 2009 ranges, the weekly rates behind them, the separate twin numbers, and what the evidence actually says about gaining more or less.
Scans and Tests in a Twin Pregnancy: What's Different
A twin pregnancy is scanned far more often than a singleton one, and the reason sits in a single first-trimester appointment. Here is what each scan is for, why dichorionic and monochorionic twins follow different calendars, how Down's syndrome screening behaves with two babies, and what the glucose tolerance test still cannot tell you.
The 5-1-1 Rule: When to Go to the Hospital During Labor
The 5-1-1 rule is shorthand: contractions 5 minutes apart, 1 minute long, for 1 hour. But it's a starting point, not the only signal. Here's how to read your contractions, what your provider really needs to know when you call, and the cases where you don't wait for 5-1-1 at all.
The Chinese Gender Predictor: Fun Tradition or Real Science?
The Chinese gender chart turns two numbers — lunar age and lunar conception month — into a boy-or-girl answer. Two large studies say it lands at chance. Here is the real math, and the two tests that actually tell you.
The Edinburgh Postnatal Depression Scale (EPDS), Explained
The EPDS is the questionnaire your midwife, health visitor or OB hands you after birth. Here is what each of the 10 questions is getting at, what a score of 10 or 13 actually signals, why question 10 is treated separately, and what happens next.
The Mayan Gender Predictor: How It Works and Whether It Is Accurate
The Mayan gender predictor compares the mother's age at conception with the month she conceived, then calls boy or girl on whether both numbers share the same parity. Here is the arithmetic, the folklore behind it, and what actually determines your baby's sex.
Twin Pregnancy Week by Week: What Changes, and When Twins Usually Arrive
Twin pregnancy runs on the same 40-week calendar as a singleton, but almost everything hung off it is different: symptoms arrive earlier, the 11 to 14 week scan sets chorionicity, the scan calendar splits in two after 16 weeks, and more than half of twins are born before 37 weeks.
