Why has my 9 week old stopped sleeping well?

B

I was not blessed with a baby who would sleep 6-8 bouts straight. The most I can get my LO to sleep in one sitting is 4 hours.

However, within the last week, my LO with sleep 2 hours. He's getting up like clockwork. I have no idea what happened or why this sudden change.... but mama is tired. At most I'll get an hour and a half before I have to wake again and it's SOOOO draining.

HELP!
