Nap training can be a challenging process for parents, but it is essential for developing healthy sleep habits in babies. Many parents wonder when they should start nap training their little ones. While there is no hard and fast rule, most experts agree that babies can start nap training as early as 4-6 months old. However, it is important to remember that every baby is different, and some may be ready earlier or later than others. Starting nap training early can prevent sleep problems down the line and help babies get the rest they need to grow and develop. With patience and consistency, parents can successfully teach their babies to take restful, regular naps.
