When does a fetus reach developmental milestones?
Fetal development is nothing short of a miracle. Our creative God has set in place these stages (and more) as your baby develops. Here are just a few highlights:
- 4 weeks: Your baby is about the size of a poppy seed. It’s around this time that you suspect you might be pregnant and take a test.
- 5 weeks: Your baby’s circulatory system is developing and a tiny heart begins to beat.
- 9 weeks: Your baby is about the size of a grape and has tiny ear lobes forming.
- 13 weeks: Your baby now has fingerprints.
- 17 weeks: Your baby’s bones (formerly cartilage) is hardening.
- 21 weeks: Your baby’s movements include stronger kicks.
- 26 weeks: Your baby is breathing amniotic fluid in and out — helping develop their lungs.
- 28 weeks: Your baby’s eyesight is developing.
- 31 weeks: Your baby can move his or her head from side to side.
- 34 weeks: Your baby’s central nervous system and respiratory system are both developing significantly.
- 37 weeks: Your baby’s development becomes stronger and stronger. You could go into labor any day now.
