There are add-ons like Child 1, Child 2 and so on, which can sometimes be effective in improving performance, but are more expensive in the long run that any of the other apps, due to undocumented features and sub-routines that pop up unexpectedly, like Swanky Pram/Carseat Combo 1 and Too-small-in-a-couple-of-weeks clothes 999, and later Driving Lessons 17 and University Fees 18.
There is also the possibility that running Child 1, Child 2 and Child 3 in rapid sequence could seriously affect the smooth running of Blessed Sleep 24/7 and hence Marital Harmony. Even Child 1 often achieves this.
Shall we reboot our cartoons thread again? 😁
