Dale Rainbow Baby Trait by DaleRune at Mod The Sims 4

Occasional Buffs:

One, ‘Lucky’, boosts the increase of friendly LTRs by 1.3x, gives all happy emotions a 1.5x multiplier, and increases the autonomy of friendly/chatting interactions, particularly of ‘Hug Lovingly’.
The other, ‘Reminiscence of an Unknown’, allows a special interaction called ‘Miss Them’ to play out, initiated by the rainbow baby to their parent; that leads to its own buff for the parent.
I’m still trying to refine their timing, so please be aware of that.
Other Features:
There’s another always-on interaction initiable by the parent, ‘Give Extra Love’; it activates happy buffs on both sides.
This trait does not affect need decay, nor does it have any whims or proximity buffs.
