Parent components show over child form

I've been following the below page in order to have a child Form that I can click on its components (such as an edit) and have proper focus:

Working with MDI Forms in Delphi

The problem now is that the components on the parent Form show on top of the child Form. If I use the SendToBack() command for those components, they completely disappear. Here is a screenshot of what happens:

EDIT:
I have a Form with buttons and a ListView that displays client info. When I click on a client, I can click a button to view or edit that client, alternatively add a new one. The Edit/Add pops up a Form where I can input the info and save it. I'm using an OnClick event for each Edit that has a SetFocus(). That gets focus on each Edit, but then all the text is selected, so I cannot click on the line and start editing text - it just overrides unless I use an arrow first.

Initially, I used regular Forms and that's where I had the focus issue. MDI fixed that, but now it's the parent components that show on top of the child.

Concerning MDI forms: that is how MDI works. The main form is not supposed to have anything else than a menu bar and optionally a toolbar, aligned alTop. The child forms use the rest of the space. Well as @RemyLebeau suggested, you can add other controls too, if you align them.

But it turned out that the actual problem with using ordinary secondary forms was that the text in an edit control on the secondary form becomes selected when you set focus to the edit control in a button click. That is easy to change, right after you set the focus to an edit control:

Edit2.SelLength := 0; // nothing selected, cursor at beginning

Edit3.SelStart := Length(Edit3.Text); // nothing selected, cursor at end of text
