Hello Adullstudent,

For me, youngest would suffice. Not really sure if there is a word for that. If there is, please post it. Thanks.

Another way to name it, it´s Benjamin coming from the Old Testament and referring to the youngest kid in a family

Hi adullstudent!

The youngest member of a family or a group is called 'baby'.

Hi Adullstudent,

You could call him/her Lastborne.

Hope it helps.

Is there any specific name for a girl and boy?

No, there isn't. It would be 'the lastborne male' or 'the lastborne female'. However, 'lastborne' is somewhat archaic: 'youngest male' or 'youngest female' is perfectly OK, and more natural.

To refer to the last born we often use, 'the baby', as in,

She's/He's/You're the baby of the family. Some families have pet phrases; the littlest; the littlest kiddlence; the pup; ...

I've even heard adults referred to as "the baby in the family".

Maybe it's a BE vs AmE thing, but I think saying 'youngest male' or 'youngest female' sounds distinctly "clinical" (i.e. unnatural).
