Okay... so, as we all hopefully know, new dwarven mothers carry their offspring around with them until the child is old enough to walk on its own.
This is, in actuality, NOT the best-case scenario in certain cases.
One of my hunters (this was a whie ago, I forgot her name) bore her husband's child. She carried the child around with her while she hunted, and that was fine for a while. She was a good hunter and kept her child safe. Until, one day, she was ambushed by goblins. She shot two of them, and then judiciously decided to book it towards the fortress. The goblin bowmen shot in her general direction for a while. One of them eventually had a lucky shot, and hit the hunter. Right in the (get ready for it) BABY on her back. The ambush was defeated, all goblins killed, and their stuff melted/traded away. But one dwarf was injured. The huntress mother carried her baby around still, disregarding the baby's crying. The baby, unable to rest in a 'hospital' bed, had one broken and one mangled arm, one broken leg, and some bruises in other places (the bruises healed, actually). Then, on the baby's third birthday, it was old enough (not necessarily healthy enough) to walk, so the nuntress mother simply dropped the baby on the ground and left it there while she continued her hunt. The baby was rescued, given a bed, food, and water, and eventually recovered. It took two years.
A year afterwards, an update came out ad the world was deleted so I could try out the new features =P
