I have learned a few things since becoming a mother. But the one thing that I have learned that makes me so very sad, is that I will not have my kids for very long. My 4 year old is a completely different person than her 2 year old self. I miss the 2 year old. I was holding my son a little while ago, as he told me about his sticker picture that he did, and I started to miss him. I know what will happen with the second that I did not know with my first - he will be gone soon. I am really going to miss my little man.
