Got the same Problem, children are starving and dying.
Solution for the Moment, make them 3 Years old, then you can feed them/they eat themselves

I have the same problem, I eventually just gave up after losing multiple kids to starvation and removed the mod

One more here. Commenting for whenever a solution is found.

Another unfunny workaround: put them in prison.
If you draft a pawn you can try and put any other pawn in prison, usually ends up in a fight xD but you can put babies in prison without any resistance and they will be fed like any other prisoner. Also they cannot break free because they cannot walk.
You just need to "retake" them once they are old enough to walk .............
(and make sure you dont recruit them too soon xD)

Also you cannot put clothes on them without being able to walk so be sure to have temperature in the right zone :( Strange game is strange in the funniest details.

guys I've found a non invasive work around, shedule an medical operation like administering drugs to them and disable you surgeon from working on them thru for example zoning now they will be considered patients and will be feed.

never mind its ♥♥♥♥♥♥♥♥

Best workaround I came up with was adding an operation of Penoxycyline to them every few days, or at least when the 'Starvation' warning came up. Though the pawns have to be doctors in order to feed them, that way they carry out the operation. You can also suspend it before the operation but after they're fed if you want to save on the drug.

I'm not sure what mod it is ( Might be War crimes expanded. ) But you can put the pawns into an artificial coma and then they're tended too and fed.

My workaround for already born childrens you can't feed :
1: Enable Development mode on.
2: Center top, click Open debug actions menu
3: In the Pawns section, look for T: Force Birthday or T: Make +1 year older

This problem still exists, does the maker of the mod even care?

Children and babies is a good work around for this.

I will have a look at it / let me know if it still persists for you in 1.5

I will try to to put in an option to at least be able to feed them like a hospital patient, BabiesAndChildren ist still probably the better option for young children but it should at least be functional that way.
