#asktheexperts My 3 month old does not pee for 5 6 hours straight at night. That's the only stretch she doesn't pee for this long, otherwise she pees at regular intervals throughout the day. Is it something to do with her deep sleep, and that's the only long stretch she takes at night. I have been monitoring this for more than 5 days now. Kindly advise if this is normal or should check for dehydration.
