I just started a village on "hard" and had that event happen just after getting the hut built.

I actually said "drink it" this time cos it was one of my guys (vs a female) trying to .. that gave me 2 kids and 3 adults.

It turned out to be really lucky cos the next event I had was the "bad weather wiping out the stored crops" one.

The luck was having 2 kids to grab mushrooms kept them from starving until I had enough tech points to get crops into the field.
