Is this form of bonding appropriate?

So from what the story says the is a pastor and his granddaughter bonding. 
In my opinion I don't feel like anyone should take baths with anyone. Not mother and son. Not father and daughter. Not mother and daughter or father and son. It's just not my personal preference. But if anyone was to take a bath with the child i'd prefer it be a direct parent instead of extended family members. Although I don't think it's a necessary bonding technique. Of course my 1 year old peeps around the corner while I'm in the shower and if we're in a rush for time I might just pop her in the shower with me, but I'm pretty sure (and by that I mean I'm 100% sure) he dad doesn't. She tries to get in with him but he'll just call me to come rescue him 😂 how do you feel about family bathing with your child?
