Last night Jack woke every 2 hours, sometimes for a feed, sometimes for a burp. It wouldn't have been so bad if it had been a once-off. The previous two nights I had the hardest time putting him to bed. Monday night he didn't sleep till 2am. He kept crying and spitting up from 10pm - 2am, and then woke up again at around 5am, 7am, and 9am. The night before was the same except it was from 8pm to midnight. Hence, presenting zombie mom.

Possible causes? They may be separate as last night's 2-hourly thingy seems different from the puke fest the two nights before. Anyhoo, here's a few speculations:

* Growth spurt
* Teething
* Caffeine - been having green tea daily
* Food I ate: dairy, etc

Most likely culprit: growth spurt. It ties in with his age - 10 weeks.

Spoke too soon about feeling lucky. Heh...
