Hey dolls! I’m Kourtney Kardashian, proud mommy of my delicious 5½-month-old Mason Dash Disick. His handsome daddy is my boyfriend Scott Disick.

Motherhood has most definitely changed me and my life. It’s so crazy how drastic even the small details change — in such an amazing way. Even silly things, like the fact that all of my pictures on my cell phone used to be of me at photo shoots — conceited, I know! — but now every single picture on my phone is of Mason.

My son changes so much every day. Yesterday, he started getting ticklish under his arms and laughing hysterically! It’s beyond cute. While Khloe and I were playing with Mason last night, he got up on all fours and was moving all around desperately trying to grab a toy. When he finally scooted himself over to the toy, he stuck it straight in his mouth and was so proud of himself!

I could stare at him for hours! He has brought more love and joy into my life than I ever imagined.

Let me ask you all: Do you kiss your baby on his or her perfect little lips? I can’t control myself and kiss Mason on his lips all day long, kiss his chubby thighs and little toes. And his auntie Kimmie can’t resist her Mason kissing either. She basically makes out with him!
