DS is just over 8 weeks and until this week has been a pretty good sleeper. We had very frequent wakes our first couple of nights home from hospital but he then quickly started sleeping in 3hr stints at night, increasing gradually to 4 or 5 hours, even a couple of 6 hr stints a week or so back. But the last few days something seems to have changed and he's started waking every couple of hours (or even more frequently) during the night! I'm aware this is pretty standard for babies his age, but seeing as his sleep was so much better before I'm confused as to why he seems to have gone 'backward'...
