Sleep disorders in children: causes and keys to improving children's sleep

Children's sleep is essential for their physical, emotional and cognitive development. Without adequate rest, little ones may become irritable, struggle to concentrate and experience problems with growth. In this article, we talk about sleep disorders in children and how to treat them. Keep reading.

Causes of sleep disorders in children

Not following a sleep routine, stress or anxiety caused by new situations such as starting school, the arrival of a new baby brother or sister, constant screen exposure, especially before bedtime, or medical problems such as allergies, asthma or sleep apnoea can all be behind the sleeping problems our little one may be experiencing.

Sleep disorders by age

Children's sleep varies according to age, and sleep disorders in children can show up in different ways:

Sleep disorders in children aged 1 to 2: During the first years, children are still consolidating their sleep patterns. Some have frequent night waking or find it difficult to sleep. This is usually linked to the transition from daytime naps to night-time sleep, night terrors or separation anxiety.

Insomnia in children aged 2 to 3: this is characterised by difficulty falling asleep, frequent waking during the night or dependence on objects or people to sleep.

Insomnia in children aged 6 to 12: At this stage, it may be linked to school-related stress, too many after-school activities or even the use of electronic devices. It is essential to teach children relaxation techniques, establish a routine and limit screen time before bed.
