Oh Congrats on your new little ones
You're gonna have lots of love in your house for a very very long time
I have two little ones too
and it's not that much more work
Just be aware that you're going to have to keep both eyes always open
and BEWARE of those silent periods
also ... in about a month
they will be jockeying for alpha position so there might be some heated fights
unless there is yelping involved don't sweat it
let them sort it out
