As long as the baby likes it, it is no problem to be in the Yo Baby rocking chair. You can also let your baby take a nap in the baby rocker, and it is recommended that you use the lowest or median position to ensure optimal sleep comfort. However, young babies should not remain in the same sitting or lying position for too long. Therefore, it is recommended that you pay close attention to your baby's needs and constantly switch between baby rockers and other devices, such as baby carriers, your arm bends, strollers and cribs to ensure that your baby feels comfortable.
