Photos and feelings of nostalgia

I've been potty training my oldest son and have tried so hard not to lose my temper with him. It's very trying on my patience and I do what I can. He has gone from "It's ok accidents happen" to a swat on the bum for deliberate disobedience and lying. The trick is maintaining consistancy for the most part. I've wanted to scream into a pillow, because of the advice I've been given and what definitely won't work. I don't want to admit it, but I'm sure that my 4 and a half year old son is NOT ready to train. Although my three year old is :S

Anyway I was looking at some old photos and came across this.

This is the little boy I was getting angry at. This is the little boy who made me so frusterated today.
I'm not going to lie, this made me bawl my eyes out and even now I'm still teary eyed. I think I need this picture printed and placed on my bathroom door to remind me to be patient with him and show him the love he needs right now.
When looking at this picture down the road, I don't want to cry again. Hopefully the next feelings of nostalgia are filled with happiness and not regret.
