How to pass the parameters from Tabbed page to child pages of tabbed page

I'm passing one parameter from one page to the Tabbed page. I want to use that parameter in all child pages. How can I pass that parameter to child pages.

Tabbed Page XAML:

<?xml version="1.0" encoding="utf-8" ?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
            x:Class="VSS.MasterPages.VendorScheduleTabbedPage"
            xmlns:views="clr-namespace:VSS.MasterPages"
            BarBackgroundColor="#f2f0f0"
            NavigationPage.HasBackButton="False">

    <NavigationPage.TitleView>
        <Button BackgroundColor="Transparent" Image="back.png" BorderRadius="10" BorderWidth="2" BorderColor="#375587"  HorizontalOptions="StartAndExpand" WidthRequest="50" ></Button>
    </NavigationPage.TitleView>

    <TabbedPage.Children>
        <NavigationPage Title="Day" Icon="calendarIcon.png">
            <x:Arguments>
                <views:DaySchedulePage/>
            </x:Arguments>
        </NavigationPage>
        <NavigationPage Title="Week" Icon="calendarIcon.png" >
            <x:Arguments>
                <views:WeekSchedulePage/>
            </x:Arguments>
        </NavigationPage>
        <NavigationPage Title="Month" Icon="calendarIcon.png">
            <x:Arguments>
                <views:MonthSchedulePage/>
            </x:Arguments>
        </NavigationPage>
    </TabbedPage.Children>
</TabbedPage>

TabbedPage CS code:

public partial class VendorScheduleTabbedPage : Xamarin.Forms.TabbedPage
    {
        private VendorCustomerVM _customerDetails;
        public VendorScheduleTabbedPage(VendorCustomerVM customerDetails)
        {
            InitializeComponent();

            _customerDetails = new VendorCustomerVM();
            _customerDetails = customerDetails;

            On<Android>().SetBarItemColor(value: Color.FromHex("#6699FF"));
            On<Android>().SetBarSelectedItemColor(value: Color.Orange);
        }

        override protected void OnCurrentPageChanged()
        {
            base.OnCurrentPageChanged();

            if (this.CurrentPage.Title == "Week")
            {
                MessagingCenter.Send<object>(this, "Week");
            }
            else if (this.CurrentPage.Title == "Month")
            {
                MessagingCenter.Send<object>(this, "Month");
            }
            else
            {
                MessagingCenter.Send<object>(this, "Day");
            }
        }
    }
