This babies things suffers a bit from trans-Atlantic translation.
Here, when we refer to "babies", we mean literally pre-toddlers in their cribs surrounded by stuffed animals and snuggly blankets.
You might address your wife as "Hey, baby", but the plural definitely does not work. Honey, sweetie, dear, darling are all acceptable, but I think it is best to have a customized nickname for your beloved. I will not share those with you. I never kiss, nickname, and tell.
If you mean hot women, those are "babes". Some would appreciate the purported compliment and some would not.
I'm not big on "babe" myself. It seems too seventies guy to me.
"Hotties" is very '90s. It may pass.
PS: I use "sweetie" here when I am being ironic.
I do not seek; I find.
