Do you miss your one year old being littler?

I'm having a sad moment now. I am looking through my pictures on my phone and having a little moment. He was just so little and now he is so big. His personality is so funny and when he loves someone he loves hard. He is my best friend and I love him more than I could love anyone. I do also have a two month old but it is always the thought that my first baby is growing so fast and I can't stop it.
