Sims cannot cook or put away food. Infants cannot eat baby food

That sounds like a routing fail in both cases.  I'm not sure on the baby chair, but for the fridge, look to see if there is enough room in front of the fridge and nothing is overhead and low hanging.  Some light fixtures and the hanging pot racks are usually the case for route blocks.  Another thing to look at is if you have used any of the placement cheats to place anything on top of the fridge (MOO, F5, Alt, 0 & 9) and didn't get the item placed high enough to clear the fridge.  And you might try moving the fridge somewhere else as a test to see if the sim can get into it then.  And lastly, one thing I did when building one of my lots was place the fridge with MOO on in the same place where I already had a base cabinet, which blocked the fridge so moving the fridge will show you if you've done that.  I didn't find that until I tested the lot in live mode.  

Hope this helps. 

I downloaded the lot from the gallery. My initial thought was that maybe the builder placed objects incorrectly with MOO as sometimes when I download a lot from the gallery, for some reason many of the builders will cause routing issues because of how they decorated the room. I removed the cabinets, any wall decor in the kitchen and moved the counters, stove and fridge to see if anything was inside them with MOO. Yet, still nothing. My sim still acts like there is no where to cook when she grabs ingredients out of the fridge. Yet, she can make salad without an issue but cannot put the salad back into the fridge. It is so bizarre.

What is the lot venue?  Residential, Residential Rental, Haunted Residential or Residential Apartment?  If is residential rental, there are issues with some of the lots on the gallery where there are some tiles a sim can't use causing a route block.

Is there a problem with the stove?  Sometimes sims get interrupted while cooking and leave a dish in the oven which prevents using the oven from then on.  Replacing the stove also doesn't fix that at times either.  That doesn't explain why you can't put things in the fridge though.

Do you have any problem placing objects on the counters in build mode with MOO off?  I could be an invisible object blocking a countertop.  I doubt that is the case though, but something to look at.  

Hope this helps.

The venue is Residential. There are no issues with putting objects on the counter in build mode nor live mode. There is nothing inside the oven.

I appreciate your help. I have tried these before.

Ok.  I have thought of one more thing you can try.  Try using the point-to-point wall tool to redraw the walls of the kitchen.  Just to make sure the game sees the space as one room and has no invisible dividers.  If it's something with a floor tile, that should be fixed too.  It'll wipe out the wall paint and maybe floor tiles but those are easily replaced.  Other than that, I'm out of ideas for you.  

Hope this helps.
