Pregnancy Week 23: What to Expect
Baby's development, your body's changes, common symptoms, what to eat, and what to do this week.
Baby's development at week 23
Baby's lungs continue developing — blood vessels form, surfactant production slowly increases. Baby's pancreas develops further. Baby's hearing is sharp; baby can hear muffled outside sounds and your voice clearly. Baby's movements are more deliberate and stronger — kicks can sometimes be seen on the outside of your belly. Baby's skin is wrinkled and reddish; over the next weeks it will fill out as baby gains fat.
What's happening in your body
Your uterus is now about 1.5 inches above the belly button. Possible swollen feet and ankles. Possible varicose veins (in legs) from increased pressure. Possible mild dizziness from blood pressure shifts. Bump is large. Possible Braxton Hicks contractions continue. Possible mild back pain or sciatica.
Common symptoms at week 23
Belly button "out." Possible swollen feet/ankles. Possible varicose veins. Possible mild dizziness. Stronger kicks. Possible heartburn. Possible carpal tunnel symptoms (numb/tingling hands).
When to call your provider
Sudden severe swelling in face/hands, severe persistent headache, vision changes — preeclampsia warning. Severe one-sided pain, bleeding, signs of preterm labor. Painful, regular contractions.
How to feel better this week
Tour your delivery hospital or birthing center. Pre-register; this saves paperwork when you are in active labor. Practice slow, deep breathing — useful for managing discomfort and labor. Continue Kegels, side sleeping, daily walks. Elevate feet to reduce swelling. Take breaks at work to walk around.
Nutrition focus for week 23
Continue all key nutrients. Iron, calcium, vitamin D, protein, healthy fats, fiber. Avoid very salty foods if swelling is bothering you. Stay well hydrated (eight or more glasses).
For your partner
Tour the hospital together. Read the labor section of your childbirth class materials or a book like "The Birth Partner" — this is useful for both of you.
This week's to-do
Tour or pre-register at delivery hospital.
Is this normal?
Most people deliver between 38-42 weeks. Babies born before 37 weeks are considered preterm and may need extra medical support. Survival rates for preemies improve dramatically each week after week 24.
