"Girls, good morning, can anyone tell me if they've had a similar experience? My little one is dropping one of his daytime naps; currently, he has three 40-minute naps, sometimes one of them is 1:30. Recently, he has stopped settling down for his last evening nap, only going to sleep after a severe tantrum, and even then, it's not always possible to get him to sleep through the tantrum. In the morning, he wakes up around 6:30 and until 9:00, he keeps turning his head, periodically waking up with whimpers. Also, in the first half of the night, he sleeps very poorly, sometimes waking up and having a two-minute tantrum. What could this be? We thought we got through the sleep regression at three months, and now he's learned a new skill - rolling over. Could it be because of that?"
