What Happens in a Baby’s Body During Development

Babies are known for sleeping many hours throughout the day, but do you know what really happens in your child’s body during this period of rest?

While sleep may seem like a simple process, it is essential for a baby’s physical and mental development, with effects that can influence their health and well-being throughout life.

Why Is Sleep Important for Babies?

A good night’s sleep is much more than just rest. During the nighttime, especially between 10 PM and 6 AM, the growth hormone is released in the baby’s body, according to data from the Brazilian Society of Pediatrics. This hormone plays a fundamental role in physical growth, known as somatic growth, which involves the multiplication of cells responsible for the development of organs and tissues.

Additionally, sleep is essential for memory consolidation. While sleeping, the baby mentally revisits experiences from the day, strengthening brain connections. This phase is also important for boosting the immune system. On the other hand, a lack of sleep can increase cortisol levels, a hormone related to stress, which can lead to irritability and a weakened immune system, increasing the risk of illness.

How Many Hours Does a Baby Need to Sleep?

The amount of sleep varies according to the baby’s age. According to the Brazilian Society of Pediatrics, newborns spend most of the day sleeping, while older babies need fewer hours. Here are the recommended daily sleep averages:

• 1-month-old babies: 16 to 20 hours
• 3-month-old babies: 15 hours
• 6-month-old babies: 14 hours
• 1-year-old babies: 13 hours

From the first year onward, children need around 11 to 14 hours of sleep per day, including naps. It is important to remember that these hours do not need to be concentrated only at night but can be spread throughout the day.

The Impact of Poor-Quality Sleep

When babies do not get enough sleep, it can lead to both immediate and long-term problems. In the short term, sleep deprivation makes babies irritable and can even interfere with essential activities such as breastfeeding. In the long run, neglecting a proper sleep routine can lead to complications such as attention deficits, hyperactivity, and learning difficulties.

How to Ensure Quality Sleep for Your Baby?

Establishing a sleep routine is essential. Here are some tips to help your baby sleep better:

• Set regular sleep schedules: Put your baby to sleep at the same times every day to help them develop a natural biological rhythm.
• Create a peaceful environment: Make sure the sleeping area is quiet, dark, and at a comfortable temperature.
• Include relaxing activities: A warm bath, a gentle massage with oils, or a light feeding can help prepare your baby for sleep.
• Avoid distractions before bedtime: Reduce exposure to bright lights and loud noises to create a calm atmosphere for rest.
