First, the bad news: newborns eat and sleep on 3-4 hour cycles. By the age of three months, however, newborns can hold enough food to sleep for longer, perhaps 5-6 hours at a stretch. The key is to make sure everythingâs just right at bedtime, and that your babyâs eaten until full and content. When your baby goes to bed for the night, you go to bed!
1 After urine starts to flow, gently push in the catheter about 2 more inches, or to the Y connector. (Younger boys will push in the catheter only about 1 inch more at this point.) 2  Let the urine drain into the toilet or special container.  When urine stops, slowly remove the catheter.
This is to prevent vomiting, which can result in aspiration, and also cause severe bleeding from the insertion site of the catheter. Failure to follow this simple preparation may result in dangerous consequences. In general, small amounts of water can be consumed up to 2 hours before the exam.
