Mama's Boy

I've known my son (4 years old) was a mama's boy for a while. He's always preferred his Mommy over everyone, always. That's fine by me. Since I've been back from my week away (which I won't do again for a long time) either he's keeping closer to me, or I'm just noticing it more. Every day he comes to me 10-15 times, at least, and randomly either gives me a kiss, or hug, or tells me he loves me, or any combination of the three. I don't know how to explain what it does to me but I imagine my heart growing like the Grinch's does. Then, it kind of melts and travels through my body. I'm more than happy to have a mama's boy, and I think he's happy to be one.
