Help!

Is it normal to cry over your kids getting older I have two boys a two year old and 1 year old, this happened with my first son and the result of it was son #2. I felt better about my first baby growing older for the first year of my second babies life, but now I'm back to being so sad, is it extreme baby fever, or something else like depression?

Is it normal or is there something wrong with me?

I've Cried for 3 days straight about my happy healthy boys getting bigger. Someone please help
