Babies have been treated very badly in Sims4. I don't remember if we have seen anything new for them since the base game was released. I don't remember because I age them up to a toddler within hours of their birth. I think I do that for two reasons, number one being the fact they are tethered to an object that is unattractive and lacks style of any kind. Plus there is nothing to do with our Sim babies. I don't want to draw comparisons between iterations here, but I miss the various toys and activities the babies had that made playing with babies fun. The least the teams could have done was to add a mobile to the crib to make it seem as if the babies had more to do than lie in their bassinets and stare at the ceiling.
