DS turned 6 wks yesterday, and I think he had his 6w growth spurt a few days earlier.
Up until 2 nights ago, he was getting up every 3 to 3.5 hrs to nurse (I EBF). However, the last 2 nights, he slept longer stretches at the start of the night, making it a 5-hr stretch between feedings.
When your son wakes up every hour, is he waking up hungry or just fussy? I find that if I cluster feed him right before bed, he sleeps longer. However, DS is hard to burp... if he doesn't burp, he doesn't sleep well and stirs a lot in his sleep. Once he lets out a huge burp, he can sleep for hours.
