Today, my favorite is nothing like what it will be tomorrow

Lauren has gone through lots of favorites fazes. For example, she used to love applesauce and mac and cheese, now she loves pizza pie. She used to love Blue's Clues, then Nemo, then Toy Story and now it has shifted to Dora and JoJo.
I guess her tastes will change more and more the more stuff she is exposed to, but it's hard to keep up. I suppose I need to hold on tight since right now her tastes change based on what I expose her to, but when she starts having friends on her own and going to school, I'll never stand a chance.
Why do I feel like that is just around the corner? I'm not ready.
