Day 30 postpartum
In short: what happens on day 30 postpartum?
On day 30 postpartum your baby turns one month old and it’s time for the one-month check. Weight, length and head circumference are measured and general development is assessed; in many countries the second hepatitis B dose is given now (this follows the Turkish schedule; please check with your doctor in your own country). Evening crying and wind often start in these weeks and, for most babies, ease markedly by months 3–4.

What’s happening in your body?
Your womb is now very close to its pre-pregnancy size; for most mothers bleeding has stopped or become a light discharge. Stitches and a caesarean wound may look healed on the outside, but the tissue takes a few months to regain full strength. It is completely normal for some pregnancy weight to remain.
Your baby today
A one-month-old looks at faces, startles at loud noises and may try to lift their head briefly during tummy time. Colic is unexplained crying in a healthy baby for more than 3 hours a day, on more than 3 days a week; rocking in your arms, white noise and tummy massage can soothe.
Feeding and nutrition
At one month your baby’s stomach reaches the size of an egg (80–150 ml); feeds may become a little less frequent and longer. For wind, burping after feeds and checking the latch are usually more effective than cutting foods out of your own diet.
Emotions and rest
You have a whole month behind you; notice what you have learned as well as the hard moments, and don’t hesitate to ask your own questions at the one-month check.
Care and hygiene
After a vaccination, mild redness on the leg and grumpiness are normal; don’t put anything on the injection site, and comfort your baby by breastfeeding.
Tips for today
- Write your questions on your phone before the one-month check
- Take your baby’s vaccination record and health record book with you
- For evening crying, try a dim, calm room and a routine repeated every day
When to seek medical help
See a doctor without delay if your baby has a temperature of 38 °C or above, a high-pitched cry that can’t be soothed, projectile vomiting, or refuses feeds and seems floppy; a fever in a one-month-old is always an emergency.

Frequently asked questions
Which vaccine is given at 1 month?
Schedules vary by country. In some, including Turkey, the second dose of hepatitis B vaccine is given at the end of the first month, often on the day of the one-month check; in the UK, routine vaccinations start at 8 weeks.
At what age does colic go away?
Wind and colicky crying usually start at weeks 2–3, peak around week 6 and ease for most babies by months 3–4.
How much weight should a one-month-old gain each week?
Once back to birth weight, about 150–200 g a week is expected. Your paediatrician will review the growth chart at the one-month check.
