Is by having your baby sound asleep during the photoshoot. A great way to do this is by making the baby take a warm and long bath approximately 1 to 1.5 hours prior to the scheduled session The baby usually gets soothed, relaxed, and sleepy after the bath.
Prior to the session, spend 1.5 to 2.5 hours playing with the baby to try to keep them awake. It is important that your little one must not fall asleep in the car on the way to the location. By keeping them awake, the baby will be exhausted when they arrive at the studio and will easily fall asleep just before the session begins.
