24 Weeks Pregnant

Baby’s Development

Fetus ~30 cm (cantaloupe), weight ~600 g [1]. Viability achieved. Lungs developing rapidly: bronchioles branching, blood vessels forming, surfactant beginning production. Brain: complex folding (gyrification). Skin: less translucent, still wrinkled. Eyes: fully formed, fused eyelids. Ears: fully functional. Movement: very active, partner can feel from outside. Sleep-wake cycles distinct. Responds to sound (startles, calming). Responds to touch (pushes back when poked) [2].

Pregnancy Symptoms

Energy OK, may wane. Symptoms: backache, heartburn, constipation, leg cramps, mild swelling, headaches, Braxton Hicks. Uterus ~4-5 cm above navel. Partner can feel kicks from outside. Round ligament pain, possible sciatica, pelvic pain. Glucose screening this week (24-28 wk). Possible swelling in feet/ankles, fingers. Heart rate 80-100 bpm [2].

Body Changes

Uterus ~4-5 cm above navel, palpable. Weight gain: 16-23 lbs by week 24 typical. Bump clearly visible. Stretch marks, linea nigra, melasma, visible veins, varicose veins. Breasts 2 cup sizes up, colostrum may leak. Possible “pregnancy mask” (melasma). Skin: oilier, breakouts, or drier. Possible carpal tunnel [2].

Tips for Week 24

• Glucose screening this week (24-28 wk) — 1-hour test: drink 50g glucose solution (Glucola), blood drawn 1 hour later. < 140 mg/dL = normal. Positive screen → 3-hour GTT (gestational diabetes diagnosis).
• Address swelling — counterintuitive: more water = less retention. Compression socks (15-20 mmHg), elevate legs, don’t stand for long periods, low-sodium diet.
• Begin formal kick counting (some providers start now) — 10 movements in 2 hours, once daily, when baby is active. Lay on left side, drink cold water, count.
• Address pelvic pain — if SPD, PT referral, support belt, avoid stairs/heavy lifting, side-sleeping with pillow between knees.

Things To Do (Checklist)

• Get glucose screening (1-hour, 50g)
• Start formal kick counting if OB advises
• Address swelling: hydration, compression socks, elevation
• Treat pelvic pain (PT, belt, side-sleeping)
• Schedule childbirth class (20-24 weeks ideal)

Frequently Asked Questions

Q: Glucose screen came back elevated. Now what? A: ~15-20% have positive 1-hour screen. Doesn’t mean GDM. Need 3-hour GTT (100g glucose, blood at 0, 1, 2, 3 hr). 2+ abnormal = GDM diagnosis. Dietary management, possible insulin [1].

Q: I failed the 1-hour. Is the baby OK? A: Most pass the 3-hour. Even with GDM, outcomes are good with management. Risk factors don’t change the baby now; management does [2].

Q: How often do I do kick counts? A: Once daily, 10 movements in 2 hours. Best when baby is active (after meal, evening). Less than 10 in 2 hrs → eat, drink, lay on left, try again. 2nd low count → call OB [1].

For Dads

• Hand-on-belly ritual nightly — you’ll feel the kicks now. Reading, singing, or just talking while hand is on belly. The connection is real.
• Build the postpartum plan — who visits, when, how long, what meals, what help. Communicate to family/friends now. Boundary-setting is love.
• Make freezer meals — 5-10 portions easy to reheat. Soups, stews, pasta sauces, breakfast burritos, oatmeal cookies.
• Read The Expectant Father Ch. 21 — viability, third trimester preview, your role deepening.
• Pray for continued lung development — surfactant production is the next critical milestone for first breath.
