L at 6 months (and some change)

We had L's six month visit at our pediatrician's office last week.  Really, just something for momma since we don't vaccinate--I like to know how my kids are growing, and boy, is this one growing!  L weighs 19 lb, 14 oz at 6 months and 2.5 weeks.  For reference, at least in our experience, E was 18 lbs at 2.5 years old.  She is now 29 lbs at 4.5--I knew she was small, but he is definitely on the opposite end of the spectrum!  He grew 1.5 inches and 2.5 lbs since our last well check in February!  Yay for momma milk because that is all he is getting still, besides the occasional sippy with water in it, which is just hilarious, in his opinion!  He has been on hands and knees for a few weeks now, and just last Thursday, took his first few crawls!  He is practicing this skill all the time, although he doesn't take more than a couple crawls at a time so far!  Of course he army crawls all over the house, and recently discovered that he can follow E around to his delight (and her occasional annoyance) wherever she goes.  His first tooth poked through March 31st-the bottom right one, and #2 is working now--should be poking through any day!  I can't believe he's already more than 6 months old!
