Sleep training a toddler can be a daunting task for any parent. The duration of the process can vary depending on several factors such as the child's age, temperament, and sleep habits. Typically, it takes around 2-4 weeks of consistent effort to establish a healthy sleep routine for your toddler. However, it's important to note that every child is unique, and some may take longer or shorter than others. It's crucial to have a well-planned approach and stick to it with patience and consistency. Sleep training can be challenging and tiring, but it's worthwhile in the long run, as it helps your child develop good sleep habits that will benefit them throughout their life.
