Ok understood.

So I need to download the header.php file from the parent theme using FTP and then just transferring it to my child theme? Would you recommend this? Will this affect a lot for future parent theme updates?

I’m trying to add google tag manager on the site and I need to add two scripts of code one in between the header tags and another one in between the body tags, but I cant find a way or plugin to automatically add a script in between body tags. The only way I have found is by editing header.php, any recommendations?

Best,

Jon
