There is a phrase that says: "When you have children the days are long, but the years are short", it really is very true, I remember when my daughter was a newborn baby, the days seemed eternal, she cried, breastfed, cried, breastfed and so on, days and nights passed, until suddenly she was 3 years old, then 5 and now 7 years old, I don't know when it all happened, these days I happened to be looking at her photos and videos from a couple of years ago and my husband and I can't believe how much she has changed, she doesn't speak the same anymore, her face is a little different, it's as if our daughter changes every year. I perfectly understand what you feel, it's scary and exciting at the same time.
