What's Happening With Your Baby This Week?

  • The baby is building its own immune system; antibody transfer from mom via the placenta is at its peak.
  • IgG antibodies received from mom are being stored to protect against infections in the first months after birth.
  • The pupil can dilate and constrict in response to light.
  • Bones continue to harden, but the fontanelles (soft spots) between skull bones will remain open.
  • The baby is gaining about 200 grams per week; fat accumulation continues rapidly.

This Week's Tips for Mom

  • Practicing breathing techniques would be wonderful; you can learn to relax by inhaling for 4 seconds and exhaling for 6 seconds.
  • Making rest your priority is very important; your body needs energy to prepare for delivery.
  • You might consider meeting with a lactation consultant; getting information before birth can help increase breastfeeding success.
  • You may feel groin pain (round ligament pain) in the pelvic area; avoiding sudden movements can help.
  • Pre-washing your baby's items (clothes, sheets) with baby detergent would be a nice touch.
Tip of the day: Breathing techniques like Lamaze can greatly help with pain management during labor. Regular practice helps you internalize these techniques so you can apply them automatically during delivery — it can make a real difference.
