V.,
I was offered a position when I was pregnant with my first son that would allow me to work from home and not have to worry about child care. As it ended up, my amazingly supportive, current employer was willing to increase my salary to cover the cost of child care so I didn't leave. Soon after Jacob was born, I realized that there was no way I could have held the at-home position with my son in the house. And now, at age two, I realize that it would be literally impossible to maintain a fair level of work with my son around.
If you don't mind me saying, it's summer time. I feel that it's a lot to ask of your boys to not want to run around, be rowdy, be outside and have fun. Since I can remember, my youngest sister has been in summer camp with the church or the park district. She's now 15 and a 2nd year counselor at the church-camp, getting paid and LOVING it.
Another option would be hiring a teenager or college girl to come over for a couple of hours a day to entertain the boys and let them enjoy the summer weather.
Are there any SAHM's in your area that you can trade a couple of days with or that you can sit her kids in the AM and she can take yours in the PM? I'm SURE SAHM's would welcome the idea of having the morning (or afternoon) to get some things done for themselves, too.
Good luck!
