One reason sleep training might not work is because waking up at night is normal in the development of most babies during the first year. In short, don't expect a miracle, especially when it comes to long-term results. Even if the training has worked for your baby, the effect is likely to wear off, you may return to the starting point and some parents may decide to do the training again. Because of this, “crying” sleep training can be detrimental to a rapidly growing brain and a growing psyche.
Researchers have documented how, with sleep training, babies' fight-and-flight instincts are activated in the face of extensive distress, such as being left without comforting physical contact. When the distress of separation and lack of response last too long, the baby may calm down, but it is to reserve limited energy. This retreat to numbness can manifest itself as an impediment to social trust that can be carried into adulthood. These patterns can continue into adulthood when things become too stressful, preventing thinking and feeling in situations where the individual is triggered in panic or anger.
Because it can involve a little crying, many parents wonder if sleep training is bad or harmful to babies. Or if it causes unnecessary stress to babies and affects their bond with their parents. Sleep training requires planning and all caregivers to be consistent. In fact, venturing into the CIO but then failing to follow up is exactly what not to do.
For Anders, however, a self-soothing baby was simply one who went back to sleep without parental intervention; he wasn't trying to quantify his stress levels. Researchers found that fading when the father stays in the room while his baby falls asleep and the sneaking and gradual extinction that leave your baby to cry for longer and longer periods before seeing her again are effective and neither cause long-term harm. Other parents chose to sit next to the crib and caress or sing their baby to sleep, to help them adapt to the crib. There is some evidence, for example, that trial participants may feel more pressure than they would otherwise to follow a sleep intervention, raising questions about the applicability of these findings to common parents, a phenomenon that is not unique to pediatric sleep research.
Sleep consultant Alanna McGinn of Good Night Sleep Site explains that if your baby has entered the zone of excessive tiredness, bedtime becomes a battle and the stress hormone cortisol contributes to more restless sleep and frequent awakening. Meanwhile, even when done as a randomized controlled trial with an objective measure, sleep training research has other challenges. When researchers compared sleep diaries, they found that parents who had trained sleep thought their babies woke up less at night and slept for longer periods of time. There are many myths about this method that, unfortunately, contribute to suspicions about sleep training.
If they don't (because you're not meeting their needs through sleep training), you're likely to suffer the effects at a later stage. As long as your baby gets enough sleep every day, is happy and thrives, and sleeps safely, you don't have to change a thing. There are some theories that long-term breastfeeding and sleeping together may prevent a child from having a chance to develop. For example, a five-month-old baby can be expected to sleep 5 to 8 hours and a toddler to sleep 10 to 12 hours straight.
After working with thousands of parents as a baby sleep consultant, I know for sure that there are many ways to teach babies and toddlers to sleep well. From the standpoint known as “behaviorist”, sleep training methods work either by rewarding or encouraging desirable behavior (e.g.
