My Child Won’t Sleep: Causes & Solutions | IMS Sotogrande
When your child won’t sleep , the whole house feels it: you’re exhausted, your partner is frustrated, and the child is more irritable the next day. You’re not alone. Childhood sleep problems affect a huge percentage of families, and in most cases, they have an explanation and a solution.
This guide will give you the most common causes by age group and strategies that actually work—no magic formulas or controlled crying methods if that’s not your style.
Key Takeaways
- Sleep problems change with each developmental stage: what happens at 8 months is different from at 4 years.
- The physical environment (light, temperature, noise) matters as much as routines.
- Montessori advocates for a floor bed from the start, which gives the child autonomy and reduces nighttime battles.
- Bedtime tantrums usually mean the child needs more connection before letting go of the day.
- If the problem persists for more than two consecutive weeks, consult your pediatrician to rule out medical causes.
Why Your Child Won’t Sleep: Causes Change with Age
There isn’t one single reason a child won’t sleep. Each developmental stage brings its own nighttime challenges. Understanding this removes guilt and gives you concrete tools.
0 to 18 Months: Hunger, Teething, and Need for Contact
Waking at this stage is normal. A baby has a shorter sleep cycle (about 45 minutes vs. an adult’s 90) and needs to feed at night. When teeth come in, discomfort disrupts rest. And if your baby seeks constant contact, it’s not a whim—it’s an evolutionary need for security.
The solution isn’t to force independence too early. Accompanying, offering a dark and cool environment (between 18 and 21 degrees), and respecting the baby’s sleep cues makes a huge difference.
18 Months to 3 Years: The Independence Explosion
At this age, the child discovers they can make decisions, and bedtime becomes the perfect battleground. They say “no” to everything, get out of bed thirty times, or ask for water for the fifth time. They aren’t doing it to annoy you—they’re testing the limits of their decision-making power.
Giving small choices within the routine (“Should I put on the blue or green pajamas? Shall we read two stories or three?”) gives them the sense of control they need without ceding the fundamental boundary: at this time, we sleep.
3 to 6 Years: Night Fears and Overactive Imagination
Imagination runs wild, and with it come fears of the dark, monsters, and being alone. They are real to the child, even if they seem absurd to you. Invalidating them (“That doesn’t exist”) makes things worse. Instead, validating (“I understand it’s scary, I’m here”) and offering concrete tools (a flashlight, a guardian stuffed animal, a door left ajar) gives them genuine security.
From 6 Years: School Stress and Screens
In the Elementary years (6-12), academic and social demands grow. If your child won’t sleep well, ask what’s worrying them. Sometimes it’s a conflict with a classmate, other times it’s overstimulation from screens before bed. The recommendation from the American Academy of Pediatrics is clear: no screens at least one hour before bedtime.
The Prepared Environment for Sleep: What the Bedroom Needs
Maria Montessori observed that the physical environment profoundly influences a child’s behavior. This includes how they sleep. If your child won’t sleep, check these factors before changing anything else.
- Real darkness. Blackout curtains aren’t a luxury—they’re a tool. Melatonin is only properly secreted in dim light.
- Temperature between 18 and 21 degrees. A child who is too hot wakes up more.
- Silence or consistent white noise. Intermittent noises (a slamming door, the living room TV) disrupt light sleep.
- Accessible bed. In Montessori, we use a floor bed or futon from when the baby starts moving. This eliminates the traumatic transition from crib to bed and allows the child to move freely.

Sleep Routines That Actually Work
You don’t need a 45-minute ritual with whale music. You need consistency. What matters isn’t perfection but repetition: the child’s brain anticipates what’s coming and prepares to let go.
The Minimum Effective Sequence
Light dinner, bath or shower, pajamas, one or two stories (always the same ones if the child asks), a closing phrase (“Goodnight, I love you, see you in the morning”), and low light. That’s it. If you do this the same way every night for two weeks, results will appear.
What to Do When the Child Gets Out of Bed
Return them to bed calmly and without long conversation. Without getting angry, negotiating, or turning on lights. The less reaction their getting-up behavior gets, the faster it extinguishes. This requires patience, I know. But it works.
When to Really Worry
Most sleep problems are developmental and resolve with adjustments to routine and environment. But there are signs that warrant a consultation with your pediatrician:
- Loud, regular snoring (could indicate sleep apnea).
- Frequent nightmares that prevent falling back asleep.
- Sleep paralysis or recurrent night terrors.
- Excessive daytime sleepiness despite getting recommended hours.
The American Montessori Society reminds us that rest is one of the pillars of healthy development. It’s not a luxury or a parental whim.
Frequently Asked Questions
Is it normal for my 2-year-old to wake up several times a night?
Yes, it’s common at age 2. At this age, the child is going through an explosion in language and autonomy that can disrupt sleep. Wakings usually decrease with consistent routines and a calm environment. If the wakings are very frequent or the child seems distressed, consult your pediatrician.
Does Montessori recommend not using a crib?
Maria Montessori proposed a floor bed from when the baby is mobile, to respect their freedom of movement. It’s not about banning the crib, but about offering a safe space where the child can enter and exit without depending on an adult. Many families use a futon or mattress directly on the floor.
How many hours does a child need to sleep by age?
0 to 3 months: 14-17 hours (in intervals). 1 to 2 years: about 11-14 hours including naps. 3 to 5 years: 10-13 hours. 6 to 12 years: 9-12 hours. These are WHO guidelines; every child has their own rhythm, but significant deviations are worth evaluating.
Can I give them something to help them sleep?
Never give a supplement or medication without pediatric prescription. Some natural remedies like chamomile or lavender tea are common, but the most effective long-term approach is working on routines and environment. If the problem persists, your pediatrician should assess if something else is needed.
Key Conclusions
When your child won’t sleep, it doesn’t mean you’ve done something wrong. It means something in their development, environment, or routine needs an adjustment. Check the temperature, light, and bedtime sequence. Give choices within limits. And if it doesn’t improve in two weeks, seek professional help.
Your rest matters as much as theirs. If you want to see how we respect the child’s rhythms at every Montessori stage, book a visit to IMS Sotogrande and discover an environment designed for your child to grow up secure and well-rested.
