Not wanting to let go...

OK, for those that have told me that it's not that hard to let their children grow up, are very wrong. My little boy, is fixing to turn three, and I don't want him to turn another year older. It hadn't been that long ago that he was a little tiny baby boy. That I had waited very patiently for all my life. I know all mother's ask this question "Where did the time go". I honestly don't know where the time has went, because one min. he was a baby and now he his a toddler. I just wish I could freeze time and have a few more years of my little baby. My son and my husband are the loves of my life. I prayed to God for both of them. God has made me learn about patience. I wanted to have a boyfriend in school, but all the guys wanted to just be friends. So when I got out of high school I meet my husband in collage. Two years later we where married. We wanted children, that was a big reason why we married. We loved children. He has several brothers and sisters. I just have one sister. But we knew we wanted to share our life with our children. So again when we wanted to have children, God wasn't ready for us to have any. So we patiently waited. It took me a solid year to get pregnant. I had a good pregnancy, I was healthy. Then I had him and he had several medical problems. So do you see why it's hard for me to not let go of my little tiny baby. Not wanting to let go is my fear right now, I will , It's just going to be very hard for me. Because I really don't know if there will be anymore children in our life, I just don't know what God has in store for my life. I just want to hang on to what we got right now. It just hurts!!!
