I really need family advice?

Long story short, my dad is a loser and divorced his wife about 3 years ago...ever since my little brothers and my sister are going down hill fast. She smokes weed in her room....has dildo's lying around and my 11 year old brother is doing REALLY bad in school. She does not say no to them.their hygene is bad. I am 22 married and FAR away from home. Those kids have so much potential and I fear that soon it will be to late. I love my family alot but I dont like to see this going on. Whenever I call and ask the 11 year old why his homework is not turned in he says';i dunno';? Its pissing me off because im not there with them to make them shape up. I babysat them for 3 years so I grew very close to them. And now that im married and moved on I feel like I abandoned them. I dont want to cause problems with my step mom because she will just refrain from letting me talk to them...so whenever I do approche her with respect on an issue she says '; i dont know why dont you ask them ?'; helpI really need family advice?
Sorry, but looks like your dad has torn the family apart. You could go extreme and try to take the kids away from your step mom. But, as you said, you live on your own and you're married so, that might be too much of a burden. or, you could call social services and give them reason to go over there. Or, you could play devils advocate and give the cops a reason to bust your sister. Truth is, none of this has to do with you. Your step mom is being a derelict as well, which is why these kids lack and rules and boundaries.I really need family advice?
then u need to talk to your dad and let him know that its not right how hes neglecting your siblings. YES it is neglect if their failing in school, smoking dope and have poor hygiene. I think if u dont set ur dad straight hes not going to care. make more of an effort to check in and speak with them. encourage ur siblings to strive for excellence, even though u dont live nearby it wouldnt hurt to call and check in with them a few times a week. at least they know someone cares about their well being.
It is time for you to call child protective services. You can do so anonymously. Once you have made the call there will be an investigation of the home and family.
Well the only thing I can honestly say is you need to get them out of that situation because chances are, the parent in the home is not going to change her tune. You are pretty much the only hope of getting these kids close to normal again. Maybe move them in with you?
What is ur mum doing about this.... I guess u as the elder brother should talk to ur mum about this tell her that she needs to start taking of this kids before it's too late
Well what I would want to do is take her for custody of your siblings so you know they are safe and living up to their potential. If she's neglecting the kids then maybe she can't handle it or is just tired and depressed. Maybe just offer to take the kids for the summer to give her and them a break. I can see one of 2 things happening if she okays you taking them for the summer. She will realize that she can have a life and enjoy her freedom and ask you to take the kids, or she'll miss them very badly and smarten up and find ways to balance her life so the kids and her will be happier and healthier. It sounds like she's depressed and in a rut. Don't blame anyone for her depression. It takes 2 to make a marriage work. They had their reasons for breaking up. They are only people who are not invincible to their feelings. So there's my suggestion. I hope it works and helps. Best wishes to your family and you. Depression is an illness, maybe try to convince your step mom to go see a dr. about it.
