DS averages 10 hours of sleep a day. I know this because I am a data collecting freak/nerd and can't bring myself to stop keeping track on my baby app. So far today he has slept for 13 hours.
7 hours in a row last night (a first). Woke up, fed for 20 minutes, down for another 2 hours. Up for 30 minutes, down for 2 hours. And so on.
I've been pumping all day just to relieve my heaving bosoms and take this opportunity to build my freezer stash.
He also went form fitting perfectly in his 3 month clothes to having the arms at 3/4 length in just 2 weeks.
I didn't even know what to do with myself, with all the free time! I showered, did 3 loads of laundry, swept and mopped the kitchen, laundry room, and entryway, and did dishes, watered the outside potted plants - all before NOON. That is unheard of in my household.
Believe me, I am aware that this is completely a phase. And I'm so not meaning to brag on the sleep aspect. I fully expect to be up every hour when the 4mw comes to kick me in the butt. I'm just expressing my astonishment. 
 
Re: Holy Growth Spurt
Mine is now on his third lengthy nap, which I am in love with. After his nap strike, this is bliss. Not sure if its his growth spurt (or if the nap strike was), but i'm not complaining!
Although... I've gotten very little accomplished today. Had coffee with a friend and took LO to the public health clinic to get him weighed. Lots of time in the bump and internet today.
