The Sims 4 100 Baby Challenge V2 (Updated for CL / Toddlers)

Is anyone else tired of making cakes? XD Honestly if I wasn't micromanaging everyone they would eat only that. We have so much cake in this household. As it is they ended up spoiling and I throw them away.
If I had the displays I would use one for the cake and put it in a locked door. Would that work? Or it's like the fridge that even if you have more the one the food is shared?
