MOM NEEDS TO GROW UP !!!!!!

Mom's mentallity is questionable or else I have to much common sense,Last week mom decided to take a walk around the house with the kids,when she does this I know shes up to something,of course shes told the kids not to tell me but they always do, she told them she was getting a new house and they would have their own rooms,so I had to set the kids now and tell them she may get a new house but they would only visit and the new house was hers and her new baby and husband that their house was here but it was ok to go down and have fun at the new house.then I be darned if she didnt come here today to see them and the oldest she sneaks out and gives her 2,00 and tells her to see if I will let them go to her mother in laws house to spend the night,which isnt going to happen because the last time she went she fell down stair and got a 8 inch skull fracture and mom doesnt have a lic, so they are not to go any where with mom with no lic, but she still drives around with the new baby with no lic, go figure ! not theses babies! back to my story mom gives amber money and not the other two she should know they are going to see this,,well of course they do and amber tells a lie that it was change from money papa gave them to spend at store he gave them 5.00 each to spend and I knew this was not true,so I asked amber again and she said mom gave it to her here I am trying to teach theses children not to lie and to always be honest and amber feels the need to keep lying for mom.this isnt the first time she has favored amber,several months ago she gave amber 21 dollars to spend when she spent the night with her then the next week she gave nathan the same amount when he stayed with her well nina wont stay with her much because shes so attached to me.she didnt give nina any money her reply was you didnt stay, so pappa comes to the recuse and give nina the same amount. how do you have four children at the age of 25 and treat each child different this is really ticking me off, what do you think sound fair? theses kids are 5,6,and 8 then her new baby 6 months , I keep hoping she will get it right but I really dont see it
