Babies always urinate on the floor when they catch urine at night. Parents are advised to inform their babies to use the potty earlier, to take the initiative to urinate or to adjust the position of the potty correctly. The urethral sphincter and anal sphincter of infants are not fully developed until about 3 years of age. This is the physiological basis for human control of continence. Until then, the child does not have the ability to fully control bowel movements and urinate on the floor. In addition babies who wear diapers to bed at night can better control the number of nocturnal urinations earlier. Catching urine at night will affect the baby’s quality of sleep and is not conducive to the exercise of bladder function. You can also adjust the size and position of the potty to prevent your baby from spilling urine onto the floor. If after the above methods, there is still no relief, it is recommended to take your baby to the hospital for timely consultation and medical advice.
