Take advantage of sleep

Leslie • Update Mommy of a precious 1 1/2 Boy ....Hello Ladies! soo Glad to join the Glow family! I'll Be a FTM in December 4th to a Handsome blessing Baby Santiago 💙
Okay ladies, so I have a big curiosity of why many women and men tell me take advantage and sleep all you can now before the baby comes because once he is born you wont ever sleep again, is this the case with 100% of all parents? Is there something we can do?? Please share your experiance, why is this true to many people??
