HELP! About installation order and skipped stuff packs!

I have installed all my stuff packs and expansion packs etc. in a correct order. 
I installed a while ago The sims 4 Parenthood, SKIPPED the installation of the two stuffpacks, Fitness and Toddler's Stuff (my God WHY) and then installed the expansion pack Cats and Dogs.
I don't have anything else installed since Cats and Dogs.

Now I've changed my mind and want the two skipped stuff packs before I can get the latest releases. Do I have to follow the installation order and remove something before I can install the stuff packs?
Do I have to start this all over again? Can I just simply install the skipped stuff packs and then install the latest packs? Is there a program to help me in this problem? 

HELP ME PLEASE!

- apply the rest of the packs normally

Whichever option you choose I'd advise waiting for the new patch, which will be out on Origin today.
