Growth Spurt

For the past 2 weeks or so, Mason's night time sleeping schedule has been a little out of whack.  He was like clockwork for about a month, then suddenly started waking up an extra time a night whether to eat or just unswaddled.  I was getting frustrated, but also hoping it was a growth spurt which I know happens around 3 months. 
We had him weighed on his 3-month birthday and to our slight concern, he was still only 9 lbs 7 oz.  Today I had to take him to the doctor to have some what I think are spider bites checked out...and lo and behold, he weighed in at 11 lbs 4 oz!!!!  His 4-month birthday isn't till next Thursday, so that has him gaining almost 2 lbs in 3 weeks!  YEAH MASON!!!
It also means he's almost doubled his birth weight in 4 months, which makes me very happy :)
(PS, the bites are a bit mysterious and only require some topical ointment, they don't bother him at all)

Oh...and he also found his thumb :)
