I feel like this, my son's 10. He was very wanted but is an only because I can't imagine feeling more like this. Yes it got easier for me, not because the feelings lessened but there's more community support as kids get older. If your like me your actually a better parent because your trying to make up for the guilt. I feel more like the babysiter then the parent.

Look into head-start for him, I tend to do better when he was younger in daycare or a very structured day. I had the day store up my energy. Then took him home, fed him, bathed him, read him a story and off to sleep. Look into lil' dragons, ymca sports for toddlers, swimming lessons and kinder music.

As he got older we decided to home school so things got tougher. However between school, homework, and sports (lots of sports) it helps. Your only full day off is Saturday or Sunday depending on sport. It still gives you plenty of bonding time w/ family dinner and bed time stories, at ten we still do this every night. He travel's to his grandparents when we can't care for him. He has healthy microwave meals to cook if we can't. We've taught him to make cold food at the 'I can do it my self stage'. We all cook together when we can. He has more chores then most kids his age: clean his bath room/bedroom, his laundry, plan and direct dinner 1 night a week, and help with the dogs. He now regularly stays at friends houses on weekends.

I'm hoping it gets easier with age and I form more of an attachment. If I don't talk about it when he's home I'm sure he'll never find out.
