Thanks for the replies everyone.
Seems quite an even split, I prefer Dominic but my husband has his heart set on Sebastian. He can't get on board with Dom and having grown up in Glasgow, the comedian Kevin Bridges done a joke about a boy called Sebastian which I can't get out of my head. It's a lovely name but I now can't think of any other boy except the one in his joke 😂
We have another few months to consider both!
Might need to go with our compromise name Jonathan instead! x
