At 5 days old, they usually only have about 4 hours of awake sessions, within a 24 hour period. Its basically impossible lol, or you will have a very fussy baby on your hands. My son was about 3 weeks old when he started getting on a decent schedule. He would wake up about 3 times a night to eat, but would go right back to sleep. Make sure when you are getting up with baby to feed, and change...dont give eye contact, dont turn on harsh lights, nightlights are good...if the light is too bright it stimulates them and they wont want to go back t sleep right away, so keep everything in a calm environment. Also, no talking, babies start to recognize talking with play time, and quiet with night time. As long as you maintain a schedule like that so that your baby will start to recognize night from day, he/she will be sleeping through the night in no time (with occasional feedings). Patience is great quality when it comes to being a mommy lol! Its not easy, and we all have been there, just relax...these are the good times, my son is 8 months old, and I sooooo wish he was a newborn again, he wont sit still he is all over the place! Also, he is teething, and 8 month old screams are so much louder than a newborns haha! Teething is just the WORST!
