Welcome to Week 41. If you're reading this, your baby has decided they are not quite ready to leave their cozy home yet. You may feel impatient, frustrated, excited, worried, or simply tired of answering messages asking whether the baby has arrived. The good news is that most babies born during Week 41 are healthy and thriving. Your healthcare team will likely be monitoring you and your baby more closely now, helping ensure everything continues progressing safely.
