SQLSTATE[42S22]: Column not found: 1054 Unknown column LARAVEL 5.4

I can't access the relationship with with from the parent table to the child table, it tells me:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'subMeals.meal_id' in 'where clause' (SQL: select * from subComidaswhere subComidas. comida_idin (1, 2))

The strange thing is that I check the models and they are fine. In fact, I can call the relation from the child table with no problems or other food relations.

Meals table model

class comida extends Model
{
protected $table = 'comidas';

protected $fillable = [
    'id',
    'cm_nombre',
    'created_at',
    'us_id',
    'updated_at'
];

// SUS HIJOS
public function planesAlimentarios(){
    return $this->belongsToMany('frust\planesAlimentario');
}

public function alimentos(){
  return $this->belongsToMany('frust\alimento');
}

public function subComida(){
    return $this->hasMany('frust\subComida');
}

// SUS PADRES
public function User(){
    return $this->belongsTo('frust\User','us_id','id');
}
}

Model was daughter:

class subComida extends Model

{
protected $table = 'subComidas';

protected $fillable = [
    'id',
    'sbc_nombre',
    'sbc_porcentaje',
    'created_at',
    'cm_id',
    'updated_at'
];
// SUS HIJOS
// SUS PADRES
    public function Comida(){
        return $this->belongsTo('frust\Comida','cm_id','id');
}
}

As I try to bring the objects from the parent table and it gives me an error:

$comidas = comida::with(['subComida'])->paginate(5);        
    dd($comidas);

How can I try to bring the objects from the child table (and it brings them without problems)

$comidas = subComida::with(['Comida'])->paginate(5);        
    dd($comidas);

I also tried to overwrite the primary keys with $primaryKey
