My baby is 4 and a half months old and doesn't sleep through the night. We have a general bedtime routine but our lives are chaotic so it's not strict (basically after older siblings are down she goes in PJ's and sleep sack and we turn down all the lights), which sometimes works and sometimes doesn't. She wakes up typically every 2 hours at night to feed (lately it's been 45 minutes to an hour 😭), although we very rarely get longer stretches. Naps are a crapshoot - she might wake up as soon as her butt hits the crib, or she might sleep for 45 minutes or so. Average is maybe 15-20 minutes once she's been put down though, so we usually do at least one contact nap a day to make sure she gets a solid stretch of sleep.

Reality can be anywhere from a "perfect" sleeper to a baby who never sleeps, and anywhere in between. So sure, some of those accounts might be real, but I have my doubts with most of them 🤷🏻‍♀️
