It’s going to be so great for them both! Gabe is coming around- mild indifference, a little jealousy (“Daddy- take baby!” with an angry hand motion when he wants to sit on my lap and Gwen is occupying it), but, sweetness, too. He kisses her and hugs her without any direction from us- and he’s held her twice, his own idea. She’s so lucky to have such a cool guy to look out for her- and he’s so lucky that she likely won’t ever be bigger than he is. 
Shell shocked:
But, happy:
Sweet half smile and some silly faces, from the one that’s turned it all upside down for him.
