Removing Bad Moodlets (Toddler)

My toddler sims is in mourning for two days after having aged up and I just want that moodlet gone. I've tried using Sims.remove_all_buffs but it didn't work. Will the moodlet solver work or is there any other way to get rid of the moodlet without it. Or even a way to reduce the time being sad (like cry it out)
