One month stats

A whole month old! Eleanor had her one month appointment and everything is looking good! A few tidbits below:

As of 1/9/15...
Weight: 8 pounds 10 ounces (almost three pounds over her weight when we left the hospital!), 30%
Height: 22 inches, 76%
Loves: mirror by her changing table, car seat, stroller, walks, sound of the shower and blow dryer, her rock n play and swing
Hates: baths
Doesn't mind: tummy time or clothes or diaper changes
Size: mostly in 0-3 but still fits into a handful of newborn things (they're comfy in the girth, getting tight in the length)

-Still a very chill baby
-She's a strong girl - lots of great neck control already!
-Starting to smile and focus more
-Has slept a 4 hour stretch at night!
-She's a spit up QUEEN
-Still sleeping in her rock n play next to mom, but has taken 2 naps in her crib

Dad's favorite things about Ellie: 
Her tiny loud quick yell that comes out of nowhere
Snuggles
Watching Ellie and Mommy bond when Ellie eats "it's really beautiful"

Mom's favorite things about Ellie:
Streeetchers! She stretches SO BIG with her legs curled up and her arms over her head
How she rubs my arm/stomach/etc while feeding

Uh, guys? Should I do something? Or just let her cry?
