This. It was a LONG day with my little guy - no nap and up at 530am. He just wanted to be rocked tonight before bed. At first I said no - he is getting so heavy! But then he looked at me and said.."mama can I just go back to being 2 so you can rock me?" Ok dagger to the heart. Of course I got right up and held him in my arms. Even on the hard days - we have to remember how fast it goes. How fleeting each and every moment is. We only get this once with our littles.
