Which variation of Matilda do you prefer?

[Candleflamingbright]

Tilly, Tilda or Mattie?

I want a Tilly!

Tilly, although as previous people have said, nn tend to just happen. She may end up having a nn if Malteser, or Squiggles.

Matilda, I don’t like any of the diminutives.

Mattie or mati, it’s always good to have a bit of a unisex feel to a name.
Nicknames can’t really be picked in advance though people tend to fall into them. X

Tilda but I don’t like nicknames

Adore Mattie and really like Tilly. Less big fan of Tilda but I think only because it seems old fashioned to me/for an older person in some way - no idea why!
