What happens if you have a written phrase like
We were looking at the same poster(s).
but with a noun that has an irregular plural? E.g. with baby/babies, would this be the correct form?
We were looking at the same baby(ies).
Or, as a more exotic case:
We were looking at the same matrix(???). (plural is matrices)
Is there a rule or guideline for this?

It's not pretty, but the most common way I've encountered is to list both words, without the parentheses, with either a slash or the word "or" between them:
You can also try "baby (babies)", or reword in some way that avoids the question, or if the context permits, just use the plural.
