Not at all. A hug,holding her hand,a high five,all good and ways to show affection. The heavy duty things such as wrestling need to stop. She can not distinguish between right or wrong per se,so when they wrestle w her,she may think it’s okay to do so w strangers,etc. A very dangerous game. Or,when she ages,and her strength develops,she may attempt this behavior and seriously hurt her parents,Summer, Becca,etc. Think of a typical child who gets caught up w the rough housing w a parent. After a bit,parent says no more. The young child is now so wound up( wife warned him) and won’t quit. Parent now upset,child doesn’t understand why,now it’s done. Imagine Abbie who can’t absorb any of that at all!
And,I will word this carefully here. Isiah is a young man. Between 12- even now,HIS hormones are raging as well. He can’t stop his body from reacting to situations either. He knows she is is sister,but when caught up in a frenzy from the one on one physical contact,his body may not.
Same can be said about Summer/he. While Moobman and wifey constantly state she is like a sister to Isiah,thing is,Isiah KNOWS she is not and may through the years had deeper feelings than just sister/brother,and not understood it.
