I have a kid due in November so I guess I should really take advantage of the free time!
I didn't know that, congratulations mate. Make sure she breastfeeds, you will carry on getting lots of free time for atleast another 6-9 months

If I'm on a school night I don't do much in the evenings because I get home at after 8pm. So shower, quick browse of the net, family guy and bed.
When I'm off shift and not going out usually it's bath time with my son, put him to bed. Read some books together. Surf the net for a bit, tidy up the garden, read some books/magazines, family guy, bed. I used to play a lot of xbox but I've stopped gaming and I've noticed it's far easier to go to sleep and switch off than when I used to play games. I do a lot of my photo editing in the evenings as well. I don't do much in the evenings to help wind down.
