Hello! My little man is almost 11 weeks, and is exclusively breastfed. We feed on demand, which seems to be close to every 1.5 hours. He always cluster feeds at night, from about 6 or 7pm he wants to be fed on and off (takes small breaks but will fuss again within usually 20 minutes) until around 9:30/10:30pm. A few weeks ago, he started having a longer stretch during the night, around 5 hours. Up until that point he woke after 3 or so, and then subsequently every 1.5 or 2 hours. He had a few weeks of this longer stretch, anything from 4.5 to 6.5 hrs (once 7!), but it seems like the last few nights we're back to a much shorter stretch, the longest being 4 hours. He also seems to be feeding a lot more and getting less sleep during the day. Any advice? I'm trying to figure out what happened that has affected his nice long stretch at night!
