The are several different versions of the mod. (I can not do anything about the kissing looking weird for sims with different heights etc, as this requires to change the animations a LOT, and if it were easy i would think the sims team would have already implemented it)
Only thing new is that the animation is no longer as funny looking. This is a height slider based on simmythesim first height slider. Remove the old one and place this in your mods folder unzipped I added the fix to one of my downloads (heightslidertoddlerfix), and will hopefully add it them all once I have more time.
A toddlerfix is made by vectorplexus for the old sliders by simmythesim.
