What to write to a stepmum

A stepmum card has to say 'you chose this' without saying 'you replaced someone'. The lines that work name what she actually does.

Forty messages below, plus wording for when his mum is still very much in the picture.

Frequently asked questions

Should a stepmum card say 'mum'?

Only use the word you use out loud. If you call her by her name, use her name - forcing 'mum' onto a card reads as staged.

What do I write on her first Mother's Day as my stepmum?

Keep it light and grateful. 'Thank you for everything you do for us' is warm without claiming more than either of you is ready for.
