Перевод - Английский-Русский - Do you really mean that? Hello, baby!

Thanks. :-) I have only one question: Is the word "малышка" gender-related or can you use it when addressing to either a girl or a boy?

Hi!

Word "малышка" is gender related. This form is used when you address to a female-speaker.
When you address to a male-speaker, you should say "малыш".
Word "детка" refers both to a male and a female.
Word "крошка" may be used only when you address to a female.

Thanks for making that clear. :-)
