Brielle at 4 months

Tomorrow, Brielle is 4 months old.  Here's what life is like for her:
-She's in size 2 diapers, but her thighs are really big and I'm considering getting her 3s when this box is over.
-She's happy 90% of the time.  She is content to sit in her chair or lay on her mat and look at her toys.
-She rolled over from her back to her tummy on May 31st and now will never stay still.  When I lay her on her mat, she always rolls right off of it.  The last few days, it seems like she really prefers to be on her belly... whenever I lay her down on her back, she immediately rolls to her tummy.  She likes looking at herself in the mirror, laying with her squishy book and trying to eat her blanket.  Her head gets tired after a few minutes and then she gets a little cranky.
-She has her first big cold right now.  No fever.. just a super runny nose and a bad cough.  No fun.
-She still sleeps 10-11 hours at night.  Bedtime is very, very easy now.  We give her a bottle around 7pm and then swaddle her up and lay her, awake, in her crib.  After a few minutes, she falls asleep.  She rarely fusses or fights it.  She usually sleeps until the boys wake her up in the morning.  The last few nights she has woken up at 3 and 4, but I think that's cause of her cold.
-Naps are not so successful.  She seems to always nap longer for Mike, but for me, she takes 2-3 15-30 min naps a day.  If we are out and about, she usually will sleep more.
-I love hearing her laugh!  She laughs when I kiss her chest or cheeks and it's adorable.
-She loves being raised up in the air and always smiles.
-She loves sticking her tongue out.
-She's been putting her fingers in her mouth a lot lately.
-She loves watching her brothers play.
-She's a big eater.  She drinks about 6 6oz bottles a day.
-She is outgrowing 3 month clothes and is better in 3-6 month clothes.  Depends on the brand, though.
-She still loves bath time.  She likes kicking her legs and splashing them in the water.  She's gotten so much bigger than when we first bathed her in there.
-I've started putting her hair in a little ponytail/pigtails and she looks adorable.  :)
-She outgrew her little travel pack n play and we now have her sleeping in the big one.

Four months old!!!  We go for her 4 month doc appt next week and will find out how much she weighs.
