I made 5 women pregnant, but only one gave birth. My vault can fit 34 dwellers and I only have 27 (31 if the babies would be born).

Why won't the remaining 4 women give birth?


The answer is living quarters, this expands the number of people you can have.

I had waited for 6 hours for 11 pregnant women to give birth - as soon as I put in a few living quarters I had 11 births within 3 minutes.
