Infant development: Milestones from 4 to 6 months
When something's not right
Your baby might reach some developmental milestones ahead of schedule and lag behind a bit on others. This is normal. It's a good idea, however, to be aware of the signs or symptoms of a problem.
Consult your baby's doctor if you're concerned about your baby's development or your baby:
- Has very stiff or tight muscles
- Seems extremely floppy
- Reaches with only one hand
- Hasn't shown any improvement in head control
- Doesn't respond to sounds, such as by startling to sudden loud noises
- Doesn't reach for or bring objects to his or her mouth
- Doesn't attempt to roll over or sit
- Has an eye or eyes that consistently turn in or out
- Doesn't babble
- Doesn't seem to enjoy being around people or spontaneously smile
Trust your instincts. The earlier a problem is detected, the earlier it can be treated. Above all, delight in your baby's discoveries and abilities.
