What could happen with cps? Will I lose visitation? You could lose a lot more than just visitation... you don't give your state, but you could end up with no parental rights at all. Not "mom has sole custody" but "I am no longer legally this child's parent." Meaning no visits and not even (depending on the state) the right to seek visitation, since you'd no longer be a relative.
Not trying to judge, but you do sound unstable. First time seeing your kid in two months and you give him a "time out" for "sneezing too loud"?? And then hit him for using his phone??
Damn. Having said that, a report with CPS is just that. A report. It CAN lead to a court proceeding which can lead to a finding of neglect, but it doesn't necessarily. Often CPS investigates and does nothing. Don't know what your ordered visits are, but she could definitely seek to terminate them until you get help or have them be supervised. That doesn't mean she will get it, but she can definitely try.
CPS also can't decide unilaterally whether or not you can get visitation, nor can they alter a court order without due process. They can remove children from homes without a court order in emergency circumstances, they can also set up "safety plans," and do some other things like offer services. If they remove a child, they have to go to court immediately and commence a case. Safety plans are not enforceable court orders, they're just something CPS uses so if/when you mess up they can say they tried other avenues and you wouldn't comply and so they were forced to come to court.
But what could happen? Anything. No way to say whether or not you will lose visitation - absolutely possible, even likely on a temporary basis. Don't admit to all the things you just admitted to in your post though. Say nothing. It's not a criminal case, but still say nothing unless your lawyer tells you to.
Again, I'm curious what state you're in. Many have laws which allow anonymous reporting, so I'm curious how you know "she filed a report"?
