Sleep training can be a challenging time for both the baby and parents, especially during the initial stages. One of the most common issues faced during sleep training is when the baby cries. It is essential to remain calm and patient during this time and follow through with the sleep training method you have chosen. It is also important to address any potential underlying issues, such as hunger or discomfort, that may be causing the crying. Remember that consistency is key in sleep training, and it may take several days or even weeks for your baby to adjust to the new routine. Above all, trust your instincts as a parent and seek support from loved ones or a healthcare provider if needed.
