Leading/line-spacing in text fields

Hi everyone,

As part of my form I have a box with lines that span the width of the box so that people can type on or in between them with a text field. I've inserted a text field in Acrobat and have set the options to multi-line. When I test it out though, when I type in more than one line and the text wraps to the next line, the second and subsequent lines of text don't line up so that they're either sitting just above the line or between two lines. Instead some lines of text overlap the lines.

To fix this I understand that I would need to apply some leading or line-spacing to the text or text field but I'm not sure if I can do this in Acrobat. The alternative I assume, is to just have multiple text fields but this would mean that the user couldn't press the return key when entering a second line of text. Instead they'd have to copy and paste.

I wondered if anyone could tell me what my options are here?

Appreciate any assistance.
