What Is Corrected Age and Why Does It Matter
Corrected age, also called adjusted age, is calculated based on your baby’s due date, not their birth date.For example, if your baby was born two months early and is now six months old, their corrected age is four months. So, compare their milestones to a four-month-old, not a six-month-old. Doctors always use corrected age to evaluate a premature baby's development until the baby turns 2.
Typical Developmental Milestones for Premature Babies
Below is a general timeline using corrected age. Remember that each baby’s journey is unique. Slight variations are entirely normal.1. By 2 Months (Corrected Age):
- Responds to sounds and familiar voices
- Begins to smile and make eye contact
- Lifts head briefly during tummy time
- Moves arms and legs smoothly
2. By 4 Months:
- Starts cooing and babbling
- Lifts head and chest during tummy time
- Grasps small objects and brings hands to mouth
- Recognises faces and shows excitement
3. By 6 Months:
- Rolls over in both directions
- Laughs out loud
- Sits with support
- Recognises familiar people and responds to name.
4. By 9 Months
- Sits without support
- Transfers toys between hands
- Babbles “mama” or “baba” sounds
- Tries to crawl or scoot
5. By 12 Months
- Pulls up to stand and may take first steps
- Understands simple instructions like “no” or “come”
- Uses gestures such as waving or clapping
- Shows a preference for certain people or toys
Why Some Milestones May Be Delayed
Delayed milestones in preterm babies don’t always indicate developmental problems. Delays often happen because:- Muscles and coordination are still developing.
- The brain continues maturing outside the womb.
- Illness or extended NICU stays can temporarily slow progress.
- The baby needs more rest than stimulation in the early months.
When to Discuss Concerns with a Doctor
Some differences are normal, but sure signs may need professional evaluation. Speak to your paediatrician if:- Your baby doesn’t smile or respond to voices by 3 months corrected age.
- Has trouble holding head up around 4–5 months.
- Cannot sit with support for 8 months.
- Shows little movement or interest in surroundings.
- Doesn’t make any sounds or gestures around 12 months.
What Can You Do As A Parent
As a parent, you play a crucial role in supporting your premature baby’s development. Your love, care, and patience are not just important but essential. They are key to their healthy growth. Here are some ways you can help:- Encourage Skin-to-Skin Contact: Kangaroo mother care helps regulate your baby’s breathing, temperature, and emotional security.
- Follow a Feeding and Sleep Routine: Nutrition and sleep are vital for brain growth. Maintain regular feeding intervals and quiet, restful naps.
- Provide Sensory Stimulation: Gently talk, sing, and use soft toys with contrasting colours. Avoid overstimulation or loud noises.
- Tummy Time: Supervised tummy time strengthens muscles needed for crawling and sitting. Start with a few minutes daily and increase gradually.
- Celebrate Small Progress: Each smile, sound, or movement matters. Positive reinforcement encourages faster learning.
- Attend Regular Check-ups: Paediatricians will monitor growth, motor skills, and social development. Ask questions freely — understanding your baby’s pace builds confidence.
- Stay Patient and Positive: Premature babies catch up beautifully with love, care, and consistency. Comparing your baby with others only adds unnecessary stress.
How Premature Development Differs from Full-Term Babies
| Development Area | Full-Term Baby | Preterm Baby |
| Physical Growth | Gains weight faster initially | Takes longer to gain weight than to catch up |
| Motor Skills | Develops in sync with age | Achieved based on corrected age |
| Communication Skills | Start babbling around 4-6 months | May start a few weeks later |
| Social Skills | Smiles and responds earlier | Builds connection gradually |
Emotional Health for Parents
Caring for a premature baby can bring anxiety or guilt, especially when comparing progress with other children. It’s important to remember: You are doing everything right. Seek emotional support if you feel overwhelmed. Talk to your partner, doctor, or parent groups. Mental health care for parents is as critical as physical care for the baby.Premature babies may start their journey a little earlier than expected, but with time, care, and patience, they often catch up beautifully. Their milestones might unfold at a different pace, and that’s completely normal. What matters most is steady progress, loving support, and regular check-ups to ensure their unique growth pattern stays on track.
Each smile, movement, and sound your baby makes is a sign of strength and resilience. By providing proper nutrition, nurturing touch, emotional comfort, and medical follow-up, you’re giving your baby the foundation they need to thrive.

- What is corrected age, and how do I calculate it?
Corrected age = Baby’s age in weeks minus the number of weeks premature. It’s used to track milestones accurately. - When should I worry about delayed milestones?
If your baby shows no progress in movement, response, or communication for several months, consult your doctor. - How can I help my premature baby develop faster?
Encourage tummy time, play, and conversation. Proper nutrition and sleep support growth naturally. - Will my premature baby walk later than other babies?
