Re: I'm missing CAS clothing for toddlers ONLY!

I'm not sure what packs you have so it's not clear what should be showing. The only swimwear top and bottoms (besides the diaper) for toddlers is from island living. Otherwise, they don't have any. For winterwear tops, the non-base game packs are toddler stuff, seasons, get famous, and eco living. You obviously have seasons, so that one should appear. Are any other seasons pack clothing missing for toddlers?

Are you using mods? If you are you should remove them and see if it still happens. You can also try repairing the game through Origin in case it didn't download correctly.
