I have a woman nursing a baby. I use the male tribal chief to make food every day. The woman has zero health but is still alive. The one tree that is fully grown is pretty much empty. The other two are growing in. There are only three villagers: the tribal chief, the woman, and the baby. How can I ensure survival of everyone, but most importantly the woman and baby??? The chief has more health than the woman, so I'm not too worried about him. They currently have 283 in food.

I'm keeping the game paused while I try to get to 600 in food by using the chief each day, and then I'm gonna put the game on fast speed so the baby will turn two. Is that a good or bad idea? On fast speed the nursing time is currently 102 minutes.

Yes, I think you can do that. But you must also make the woman eating for recovering health or make a potion with (spoiler) 2 cactus + 1 lotus (end of spoiler)

I reccomend the potion; even with no food, potions can help them last a little longer.

Use fast speed with caution. It takes very little time, on fast, for bad things to happen.

I'm afraid of potions right now. I only have l1 in alchemy, so it's very likely the person who makes the potion will get blown up!

you may stay in slow speed, then your nursing mother will recover health during the time she's nursing. and bring her to the food hut for eating!
