First and foremost strollers I don't know why in GRT (Growing Together) they didn't put in strollers when they know good well we can't pick up toddlers with infant in the baby carrier, they treating the Sims like pack mules they had to carry toddlers everywhere now we have Infants and they know toddlers are so slow it was shown in the Livestream so why not make strollers like they keep missing the mark it's insane.
Child Gameplay like children should ay tag, play Ms. Mary Mack, play Marco Polo in the pool, play make believe or dress up, and have more play grounds like a castle playground or even a regular play ground.
Romantic Interactions and reaction like Sims surprise proposal, Sims react to fights but they don't react to a proposal right in front of them
Walking Hand in Hand and Arm and Arm
Snuggling and Cuddling at night.
Make out needs to make a return.
