Can I request for temporary custody and have the courts order my sons father to get help?

I recently separated from my 11 month old sons father. It's been 2 months now. His house is dirty and unsafe for my child. He puts my child off on his mother and his daughter to care for him while he goes out or play video games. Which is 90% of the time... He's recently moved my son in the same room as his 11yr old daughter. I have a ton of evidence of abuse on me. House conditions. Him ignoring my child while playing games. And ect. I've also recently discovered that the reason my son has been getting sick, ear infections and diaper rashes is due to his father being cheap and not caring for him.. he buys off brand wipes and formula that upsets his body... he feeds him food once or twice a day and bottles the rest of the time which isn't good... his landlord is a well recognized lawyer and i am afraid of losing.. I plan to keep my child out of his house until he can make changes and prove he can care for him. My son lives back and fourth from households through the week...
