#AsktheExperts Good Morning Doc. My 3 mo does not pee for 5 6 hours straight at night. This is the only stretch when she sleeps uninterrupted and this long. At other times of the day/night she pees and poops at almost regular intervals. But, this stretch is bothering me. Is it something to do with her deep sleep? Should I go for her dehydration check? I have been monitoring this for last 5 days. She follows the same pattern. Thanks.
