Our two daughters are grown up and left home.I found that it wasn't the kids that stopped hobbies,but the pressure of work and relatives (illness etc.).
In the UK, you have to be careful about photographing kids these days (which is sad), but it must not stop you, otherwise you will have no record of all those precious moments (speaking from experience here!)
When I started my own business, it was very successful, but I ended up working 120+ hours a week.
It was brou8ght home to me when my wife said 'Lisa has got her bronze'
I said 'bronze in what?'
'Tap and dance'
'When did she start them?'
'six months ago!!!!'
It was then that I decided that money wasn't everything and closed my business and worked for a company and had weekends and evenings with the family!
