This is good...I certainly identify with the switch that's flipped the moment I see my son. I'm able to forget work while I'm with him, and just focus on the important things. Like Nataly, I had a hard time checking my work frustrations at the door before he was born. Some days it's literally a weight off my shoulders when I walk in the house and he runs toward me yelling "MOMMMMYY!"
