I first photographed these guys about a year ago when baby boy was just that - a tiny baby. I love families that ask me to photograph them again, it means they were very happy customers but I also get to document them growing up and I think that's quite special.
They trusted my recommendation of making use of the golden hour and kept the kids up a little past their bedtime for their session. They were so good! 
Don't be put off from making the most of the summer light and taking the kids on a mini adventure to make use of the hour before sunset (currently about 8:30pm to 9:30pm) - even if it's in your sunny garden!
