Our boy is 6 weeks old and so far the longest he sleeps is for 2 hours (only when being held) and he feeds every hour (currently for 15-20 mins).
Sleeping: 8-10 hours total (3-4 x 30 minute naps during the day / 6-8 x 1 hour maximum sleeps during the night)
Feeding: 15-20 times a day (for 15-20 minutes)
Nappies: 1-2 dirty / 5-6 wet per day
He seems to be developing well, babbling/smiling, good weight, doesn't cry a lot - but he does seem very unsettled (jerking) almost all the time.
I'm sure there's nothing to worry about, except the OH getting some down time occasionally. But the lack of sleep (and number of feeds) does sound extreme. We swaddle him, use white noise, rock him to sleep, and he mainly co-sleeps. Any advice appreciated!
