How should I sleep train my baby?

First, check with your pediatrician to make sure your baby is ready for sleep training. Most babies are ready for sleep training at about 4 months old given they are growing according to the growth curves. You can start with naps and put the baby to sleep when they are drowsy but not fully asleep. This is important because at this stage, the baby's sleep pattern become more like an adult sleep pattern and they start waking up throughout their nap and nighttime sleep to check their surroundings before falling back asleep. You want to make sure they are able to fall asleep independently in their own bed.
