Y'know what? You need to check carefully that you don't have hacks from multiple places that try to modify the same bit of code. If this happens, it's called a conflicting hack, and you have to decide which one you want to keep. Having the two in there together will certainly cause jumping.
Now, that error log mentions fridges and baby bottles, so I immediately looked to see whether you have a hacked fridge (if you do, it's not coming up in red) and whether you had hacks that affect caring for babies. You're listing that you have a hack called LessAutonomyBabyCare (from source unknown), but you also have J.M. Pescado's antibabylecture, nodroptiredbaby and nosmartmilkdrag. That could easily be a source of conflict, for starters.
Hacks from reliable sources should always come with a readme.txt or RTFM.txt file in the zip to tell you what they do, and any known conflicts with mods by other creators. You do need to cross-reference these and not blindly download anything that sounds useful
