Week 25 of Pregnancy

Baby Size Comparison in Week 25

In week 25 of pregnancy your baby measures about 35 cm long and weighs about 660 grams: roughly the size of Cauliflower. Remember these are approximate averages from standard growth charts; every baby grows at their own pace, and your doctor follows your baby's personal growth curve across visits, not a single number. If an ultrasound measures a little bigger or smaller than average, that is usually normal as long as growth continues at a steady rate.

Baby Development in Week 25

The fetus responds to familiar sounds (your voice and its father's) with calm movement and calmness, and to unfamiliar sounds with activity. The hair grows and takes its final color and texture from the genes, and the skin of the hands has become less wrinkled.

The lungs continue producing surfactant, and the capillaries branch within them. Fat accumulates at a faster pace, so the body fills out and its skinny look disappears. The fetus can sometimes grab its foot, and its movements are strong enough that your partner may see them from outside. The sleep-wake cycle is clear; you may notice it becomes active when you relax in the evening.

Your Body Changes in Week 25

Back pain intensifies with the weight of the belly, and hemorrhoids may appear or worsen. Heartburn after almost every meal, and nighttime insomnia is common.

Restless legs syndrome (an urgent urge to move the legs at night) bothers many. Foot swelling continues. You may feel Braxton Hicks contractions more clearly. Weight gain is about 8 to 11 kilograms. Emotionally: excitement to meet the child mixes with anxiety about labor and responsibility; completely normal feelings. Start thinking seriously about the birth plan and the hospital.

Back pain is eased by warm compresses and gentle massage. Nighttime restless legs improve by avoiding caffeine in the evening. Treat hemorrhoids early before they worsen. And discuss the birth plan and hospital with your partner.

Practical Tips for Week 25

• Do Kegel exercises daily (tighten the pelvic muscles for 10 seconds, then release) in preparation for birth.
• Eat small, frequent meals and chew slowly to ease heartburn and bloating.
• Move and walk a little when your legs feel restless at night; avoid caffeine in the evening.
• Discuss the birth plan with your partner: the hospital, the companion, and each of your expectations.
