Hello!
we are due baby no3 very soon and having difficulties settling on a name for him.
we already have 2 boys. DS1 is Tobias (Toby) and DS2 is Sullivan (Sully)

we’ve narrowed it down to the following:
Rupert
Austin
Sebastian

any thoughts on these names? or any other suggestions? Middle name will be Thomas.

I have a Sebastian Thomas. His brothers call him Sebby 😍

Your names are lovely.

My fav is Sebastian (Seb/Sebby/Bash) but I wouldn’t use it as you have already got an S son.

Rupert is nice. Would you call him Ruppy or Pertie?

I’d probably go with Austin (Ozzy) in your case.

I like Sebastian, but do you want two children with names beginning with S? I’m not keen on Austin or Rupert.

Austin

Rupert is just a bit wet and Woopert-y, and Sebastian has become a real supermarket name, pronounced Sebas-Chun.

I knew an Austin who was friends with my grandfather and a strong, successful man he was too!

Austin is a car
