Families growing up!

so I was thinking today that it is so strange to see my family (my sisters) growing up. I don't feel I am getting older with each passing year but for some reason in my head my 11 year old sister is pregnant and my 13 year old sister is getting married to a man who has two children that will be living with her full time, she too will be a mom. But honestly they can't be growing up because I am not getting older right? We are all still young in our heads how time does fly. I can't imagine how fast it will go with my own children. Here is a picture that was taken just 'yesterday'
