Help me come up with a nickname for a difficult-to-pronounce Scandinavian name

[hejdu]

My daughter's name is Mette which is pronounced Meh-deh.

We relocated to the United Kingdom a while ago and have yet to meet anyone who's been able to pronounce her name correctly, hence the need for a nickname.

Any suggestions would be greatly appreciated!

The singer Mette Towley seems to have the same problem. I have noticed she pronounces her name "Meh-deh" in the US and "Meh-teh" in the UK.
