Robby's absolutely a babywearing dad.
He's carrying your girls all the time, never letting you carry one for too long if he can help it. His excuse is always "You carried them for nine months, now it's my turn."
He's commonly seen with your oldest on his shoulders, her little hands in his graying hair, your youngest on him in a baby carrier or if you're lucky, both.
His little girls are obsessed with their dad carrying them, feeling like they're on top of the world when they're in their dad's arms. Sometimes when you try offering to carry your oldest daughter instead of him she gives you that look that is very 'Robby' and just says something along the lines of "No mommy, daddy does it better" Robby absolutely BEAMS at this, giving you a smug smile as he picks up your eldest daughter.
Your youngest daughter even went through a phase for a short period of time when she was really little before Robby went back to work after paternal leave where she refused to let anyone but him hold her except to feed her. She quickly had to get over that when he was back working in the Pitt but she wasn't happy about it, fussing every time he would hand her over to you in the morning to head to work.
As your kids get older and they realize daddy can't pick them up anymore as easily or at all, they feel like the world has ENDED. When Robby turns down picking up your eldest daughter for the first time because she was getting too big for him to carry easily she lost it. You thought she was fine until Robby found her later hiding in her closet crying, her little voice saying to him in between hiccupped cries, "Do you not love me anymore? You said you couldn't pick me up...are you mad at me?" Robby's heart BREAKS at this. He pulls his little girl into his lap, still in the closet, and holds her close while he reassures her, holding back his own tears.
