Help with middle names.

My husband and I aren’t 100% set on names. We didn’t even have a single name picked with our last baby until we saw his precious little face.

But I’m now 30 + 3 weeks and I find myself coming back to

1) Amelia for a girl

2 Elias for a boy (pronounced like El-ly-us)

My problem is I can’t think of any middle names that flow. I litterally struggle SO. MUCH. Picking names.

Any suggestions would be appreciated.

Thankyou in advance.

(Also we don’t know the gender)
