My identical boys are 4 months old and have developed the same sleep problem in the same way, at the same time. Over the course of the night, both sleep about 4 hours, wake, then 3, wake, then 1-2 hours for the rest of the night. Given their age, hourly feeding seems to be a bit much. Both wake to nurse only (no playing), and go right back to sleep. Neither will accept any other comforting (pacifiers, snuggling, etc). I have slept in their room from time to time and there isn’t any external stimuli to startle them. What makes them wake up and why does the sleep length keep shrinking as the night goes on? Can we fix it? Oh, and they nap on schedule during the day, but not for more than an hour. ~ Katie
Dear Katie,
In order to answer your question, I consulted The No-Cry Sleep Solution by Elizabeth Pantley and Healthy Sleep Habits, Happy Twins by Dr.Marc Weissbluth. Both authors write extensively about the biological importance of sleep. Pantley explains that a baby’s biological clock begins maturing at about 6-9 weeks and does not work smoothly until 4 -5 months. Dr. Weissbluth asserts that around 12-16 weeks daytime sleep starts to regularize and bedtime is earlier. He finds that around four months of age babies become interested in things that can disturb their sleep.
Each of them underlines the importance of establishing sleep cues along with self-soothing techniques so that the infant becomes accustomed to falling asleep on his own. In response to your question about your twins’ diminishing nighttime sleep and shorter daytime nap schedule, I offer the following explanation based upon these experts’ research. Pantley writes that by six months of age, the average naps per day is two, and the total length of naptime hours are between 3-4 hours. Since naptime sleep has a great impact on nighttime sleep, do everything that you can to get your babies to nap longer during the day. Pantley suggests the following:…..
