Week 28 milestones

  • Eyes can open and close — baby can perceive light through the belly wall
  • Brain is forming complex folds and gaining mass rapidly
  • Baby is putting on fat layers, smoothing out previously wrinkled skin
  • Hiccups become noticeable to mom (rhythmic small jolts)

Tip for week 28

Third trimester begins. Start counting kicks daily — at least 10 movements in 2 hours is the standard 'kick count' guideline.
