while I am not in Parker's situation, so I can't state for fact what is going on with things..... I will say--- AlteredState I don't agree that a 3 year old is able to give "loyalty"... as you say.
It happens so much that a parent favors a child over their other children-- and it could be the case in this situation--- but maybe not..... It's hard to say---
it's just so very wrong though for an older sibling to be allowed to wall-slam a smaller child--- the smaller child may grow up expecting everyone to be like that to them.
A mother is supposed to nurture and protect--
every child they have.(IMO)
This just really hits a nerve with me-

I don't mean any offense to you or anyone here.
