0002160: Babies/infants stuck inside fortifications, can't be freed except by removing fortification
Fortifications have a problem with items that are flowing into them. The item disappears from screen when it hits the fortification. They are still listed in the stock menu. With d-b-d mass-dump the items are accessible, too.
Build a fortification. Dump some items before it. Let water push these items into the fortification.
Another thing that could be related: I have Infants sitting in fortification tiles. Trapped and abandoned by their parents. Only solution is to dig out the fortification and free the baby.
Happened while cleaning a huge water trap from clutter. Long corridor with fortifications on both sided and one tile high water. No flowing water but 0000039:0000030 dwarfs dumping items, trying to step over each other. Ceiling above fortifications.

happened with 31.04 and 31.05
No tags attached.

Do the items show up in the menu if you 'k' over them?

No, they stay hidden with k.
Zooming from the z-menu reveals the location where it should be, but the item is still not visible.
When marked for dumping the dwarf picks it up and it is revealed.

EDIT: related to 0000895 ?
Tested without fortification and disappeared too

Yup, it's probably 0000895. I'll repurpose this report to focus on the other problem you mentioned (babies stuck in the fortification), which probably isn't quite the same bug.

To clarify this.
The babies can't be dropped from above. There's a Floor. The mother is walking in a corridor with fortified walls and heavy traffic.
I have a save with two babies sitting in fortifications if needed.

This bug is quite entertaining.
When the baby is sitting in a constructed fortification you can't free it. Removing the fortification is not possible when a baby is sitting there. If it grows to a child it frees itself and walks away. If you tried to remove the construction, the job gets created once the baby is gone (death or growth).

EDIT: Observed what's causing this. The room has one and two tiles high water that is creating a constant flow. Sometimes dwarfs get pressed through a fortification by this flow, usually with "Dangerous terrain" announcement. If this happens to a dwarf with a baby, the poor baby is stuck.
That creatures can get pressed through fortifications and even grates seems to be causing this.
