When Henry came home, he was sleeping five, even six hours at night, and continued to do so until he was about three or four months old. A growth spurt caused a shift in sleep needs, he started waking up every few hours. While I was able to get us back on a consistent daytime schedule, he kept waking up at night to eat or to let us know he had wiggled an arm out of his swaddle.
We stopped swaddling so he could get used to sleeping unbound. I cut out the middle-of-the-night feeding. He's fine without it and can go until morning to eat. But he keeps waking up, consistently between three and four in the morning, and the broken sleep is starting to wear me down. It's especially hard since I had been getting full nights' sleep, then had to stop.
