Sort list by name, date and hierarchy

I want to sort the following list in the following order:

1. first by object without any parent
2. then by name
3. by year
4. by month
5. related objects should come directly after by the criteria (2-4).

So what I want to achieve is basically a tree structure as a flat list.

This is what I've come up with until now, but can't figure out how to implement the parent relation.

function monthYearCheck(a, b) {
    if(a.year < b.year) {
        return -1;
    } else if(a.year > b.year) {
        return 1;
    } else {
        if(a.month < b.month) {
            return -1;
        } else if(a.month > b.month) {
            return 1;
        } else {
            return 0;
        }
    }
}

var sortedArray = nonSortedArray.sort(function (a, b) {
    if(a.name === b.name) {
        return monthYearCheck(a, b);
    } else if(a.name < b.name) {
        return -1;
    } else if(a.name > b.name) {
        return 1;
    }
});   

This is the array before sorting:

[{
    name: "Bottom",
    id: 4,
    parentId: 54,
    month: 6,
    year: 2016,
    value: 16       
},{
    name: "Topp",
    id: 12,
    month: 6,
    year: 2016,
    value: 24
},{
    name: "Middle",
    id: 54,
    parentId: 12,
    month: 5,
    year: 2016,
    value: 14   
},{
    name: "Middle2",
    id: 118,
    parentId: 104,
    month: 6,
    year: 2016,
    value: 4    
},{
    name: "Bottom2",
    id: 5,
    parentId: 54,
    month: 5,
    year: 2016,
    value: 12
},{
    name: "Topp",
    id: 12,
    month: 5,
    year: 2016,
    value: 12
},{
    name: "Middle",
    id: 54,
    parentId: 12,
    month: 6,
    year: 2016,
    value: 4    
},{
    name: "Topp2",
    id: 104,
    month: 5,
    year: 2016,
    value: 12
},{
    name: "Bottom2",
    id: 5,
    parentId: 54,
    month: 6,
    year: 2016,
    value: 2        
}]

This is what I want to achieve:

[{
    name: "Topp",
    id: 12,
    month: 5,
    year: 2016,
    value: 12
},{
    name: "Topp",
    id: 12,
    month: 6,
    year: 2016,
    value: 24
},{
    name: "Middle",
    id: 54,
    parentId: 12,
    month: 5,
    year: 2016,
    value: 14   
},{
    name: "Middle",
    id: 54,
    parentId: 12,
    month: 6,
    year: 2016,
    value: 4    
},{
    name: "Bottom",
    id: 4,
    parentId: 54,
    month: 6,
    year: 2016,
    value: 16       
},{
    name: "Bottom2",
    id: 5,
    parentId: 54,
    month: 6,
    year: 2016,
    value: 2        
},{
    name: "Bottom2",
    id: 5,
    parentId: 54,
    month: 5,
    year: 2016,
    value: 12
},{
    name: "Topp2",
    id: 104,
    month: 5,
    year: 2016,
    value: 12
},{
    name: "Middle2",
    id: 118,
    parentId: 104,
    month: 6,
    year: 2016,
    value: 4    
}]
