What is corrected age?

Corrected age is your baby's age worked out from your pregnancy due date, not the day they were born. The HSE uses it to see how well a baby born early is developing. For example, a 10 month old born 2 months early has a corrected age of 8 months. Premature means born before 37 weeks.

How do I work out my baby's corrected age?

Take your baby's age and subtract the number of weeks or months they were born early. The HSE gives this example: a 7 month old baby born 2 months early has a corrected age of 5 months. The calculator above does the sum for you.

Should I check milestones against corrected age?

Yes. The HSE says you can work out how well your baby is developing from your pregnancy due date. So if your 10 month old baby was born 2 months early, check the milestones for 8 months. The HSE adds that most premature babies meet their milestones for their corrected age and grow up healthy.

When can a premature baby start solid foods?

The HSE says your baby's stage of development is more important than their age. Start introducing solid foods when your baby shows at least 3 signs that they are ready. They may have all the skills they need from a corrected age of about 5 to 6 months. The signs are listed below.

The 6 signs are that your baby:

• can sit up by themselves with only a little support
• can hold their head up easily and keep it up while sitting
• explores objects with their fingers, hands and mouth
• can reach and grasp for food
• opens their mouth when food is being offered
• bites or chews toys

What if my baby is 7 months corrected and not ready for solids?

Speak to your GP or public health nurse if your baby has a corrected age of 7 months and is not showing signs that they are ready to start solid foods. The HSE lists this as non-urgent advice. Use the calculator above to check your baby's corrected age first, then take the answer along to the appointment.

What solid foods suit a premature baby?

Premature babies usually have smaller tummies, so the HSE says they need to eat small amounts of nutritious foods often. Include protein, energy-rich and iron-rich foods. Breastfeeding while weaning can help your baby get used to solid foods, your milk supply will adjust, and you can breastfeed for as long as you want.

The HSE gives these examples:

• mashed or blended meat or fish that is boneless
• mashed or blended banana, avocado or potato
• lentils or beans
• porridge or fortified cereals that are low in sugar
• foods that are safe for your baby from your culture

Do not give your baby foods that can cause choking.

Are premature babies more likely to have allergies?

No. The HSE says there is no evidence that premature babies are more likely to develop allergies. If you have concerns about allergies, speak to your public health nurse or GP. The HSE also advises speaking to them if you are considering a vegetarian or vegan diet for your baby.

How can I help my premature baby develop?

You can help your baby's development by being present and taking part in their care. The HSE says to talk gently and wait to see their response before you touch them, which lets your baby take the lead. Too much at once can feel like a lot, so try one thing at a time.

• Touch: gentle, responsive touch and massage can help soothe your baby and support bonding.
• Sound: your baby can hear very well at birth. Talking and reading to them can help calm them.
• Light: bright light is stressful, so soft lighting and shade help.
• Smell: avoid perfumed products so your baby can recognise your natural smell.
• Sleep: give your baby time to rest and recover between interactions.
• Talking: your baby recognises your voice from early on, and it helps communication develop.
• Reading: it does not matter what you read. They enjoy listening and being close to you.
• Singing: the gentle rhythm of songs can help them relax, feel safe and settle more easily.

Pause to give your baby a moment to show you how they are feeling. As they grow and mature you will notice their ability to interact more.

What are the benefits of skin to skin contact?

Holding your baby directly against your skin can help them regulate their sleep, temperature and heart rate, says the HSE. It can also help your baby grow, support your milk supply if you are breastfeeding, help you learn to be sensitive to your baby's needs and cues, and increase your confidence in caring for your baby.
