"Watching this one grow into a mother of 3 has easily been the most humbling experience of my life," Matthew expressed. "The patience, power, love & empathy required to mom the way she moms is so far beyond anything I could dream of possessing. Ba, you do it all with such grace and make it look way too easy. This year, especially, would have ruined our kids if it weren't for your ability to navigate us with sensitivity and balance. Thank you for being the leader of our pack. Thank you for three beautiful kids and I'm sorry for my involvement that contributes to any ticks, cowlicks, or irrational fear of shrimp allergies. We are the luckiest."
