The correct choice is babies when you mean more than one baby. Babys is not the standard plural form in US English.
This mistake is common because many English words become plural by adding s. But baby follows a different spelling pattern. Since baby ends in a consonant plus y, the y changes to i, and es is added: baby → babies.
Quick Answer
Use babies for more than one baby.
Do not use babys as the plural of baby in standard writing.
Correct: The babies are sleeping.
Incorrect: The babys are sleeping.
There is one extra point: babies can also be a verb form. For example, “She babies her old dog” means she treats the dog with extra care. That use is different from the plural noun.
Why People Confuse Them
People confuse babies and babys because the singular word is baby, and adding s looks simple.
That works for some words ending in y:
boy → boys
toy → toys
key → keys
But baby is different because the letter before y is a consonant: b. In that pattern, standard English changes y to ies.
So the correct plural is:
baby → babies
The same pattern appears in words like:
party → parties
city → cities
story → stories
