Growing Together Items wont work

Hello, 

I am hoping someone can help me. I'm super new to Sims 4 and recently purchased the game along with all the the packs, kits, and expansions. I am having an issue with the Growing Together items. My game allows me to purchase and place them but I am not able to actually use them. For example, the crib only gives me the "upgrade"  and the "make an heirloom" prompts. That goes for the changing table and the floor playmat. Anyone know how to fix this please? :)

Thanks!
