"You should frame that," she said after he kissed her, obviously teasing him, "Remember how excited you were when it's 3 a.m. and neither of us can sleep because the baby is crying."
Though, honestly, she couldn't imagine either of them regretting it.
But teasing aside, Kate leaned over, giving him another quick peck on the lips, "But I'm happy, too babe. I think this is perfect."
