If only life was so easy

.
We have been fighting this battle for about a little over 4 years now

.
I met my hubby 5 years ago and he had his daughter, the mom came and kidnapped her and gave her to the grandma and then she went back to bad living and ended up in prison. But the grandma was raising the little guy so we went through the court system to do it right and we got full becausetody of them both after thousands of dollars and 8 months in court.
Now although we have full becausetody, the Judge granted the grandma visitation at her house, even years spring break (1 week). 1 month every summer, even years Thanksgiving, and every year Christmas break starting Dec.26th to the Sunday right before school.
It wouldnt be bad if the grandma had good kids that were Good! But every single one of them has been in major trouble. Maybe one of them works, none of them graduated. They have cops at the house on a regular basis, the youngest was just arrested for theft and they have major drug problems that this judge knows about. It is FREAKIN insane!
Get a load of this,
First is the oldest. She is aprox 35 yrs old and she has had herione fed exed to the house while living with the grandma. No sh*t! That was quite along ti'me ago, but I guess her life is still messed up.
Next is the mom of the kids. She is about 29 and is currently in a treatment hospital for 4 months of not being able to leave the hospital. She is in inpatient treatment for Meth (drugs). Not to mention, she has bought pot right in front of my daughter with her brother

. The reason she is in treatment is because she peed dirty for her parol officer. She was just released from prison in June for trying to use stolden bank cards. She was also in prison before that on drug related charges and some other stuff. And she has 3 children, two of which we have and take care of, but the oldest isn't my hubs, or we would have hi'm too.
Next is I believe is a guy who is 27. He is currently in prison for charges that I believe have to do with drugs and other stuff. I believe his sentance is for 8 years, but am not positive. He has 2 children.
Then there is a girl who is aprox 26. She is living at the grandmas house and just had her second baby. That makes two. She is very bad into drugs and drinking and has been to jail a numerious amount of ti'mes.
Then is the next guy. He is 22 and has been in and out of jail constintly.He to lives at grandmas and is to have NO contact with either child. He was released from prison about almost 2 years ago for being the shooter in a drive by shooting. Since released, he has been arrested about 3 ti'mes. For breaking and entering, drug parapanilia, assult etc...
And last but surely not least is the youngest girl. She is 18 or 19 and started doing Meth at the young age of 15, when my kids' mom introduced it to her. She is now in the same footsteps as the others and was arrested for theft earlier this year. Plus she had her boyfriend living with her at grandmas house dealing drugs out of the basement.
AND WE R COURT ORDERED TO SEND OUR KIDS DOWN THERE FOR VISITATION!
