🧠 Baby at 33 Weeks: Big Brain Leaps & Sleep Rhythms
Your baby now weighs about 2 to 2.2 kg (approximately 4.5 to 5 pounds) and measures 43 to 44 cm long — about the size of a pineapple. This week is all about the brain!
🧠 What’s Developing:
- Brain development explodes — brain folds are forming rapidly.
- Pupils react to light — baby can now differentiate day and night.
- Sleep cycles begin — baby now experiences REM sleep (yes, dreaming!).
- Bones harden, except for the skull (which stays soft for delivery).
- Immune system matures with help from your antibodies.
🩺 Fun Fact: Baby’s brain weight increases by almost 400% in the last 12 weeks of pregnancy!
💃 Your Body in Week 33: Heavy Belly, Heavier Thoughts
You’re probably feeling the full weight of pregnancy now — emotionally and physically. This week may bring back pain, fatigue, swollen feet, and a whole lot of belly.
Common Body Changes:
- Shortness of breath continues as your uterus expands.
- Heartburn & indigestion may increase due to uterus pressing stomach.
- Colostrum leaks from breasts may become more noticeable.
- Numbness or tingling in hands due to fluid retention.
- Frequent urination (yes, again!).
🧘 Tip: Try prenatal yoga, deep-breathing techniques, and warm compresses for relief.
