Nelle,
I went back working full time when Amy was 4 1/2 months old so I wasn't home for as long as you. DH is a SAHD and he went to uni and was about to start a career in IT but my income was too good not to return to work. I miss her during the day but ring her sometimes so that helps. I also have photos to look at and that helps too. I told my boss that I wanted to start work early and finish early so I start at 7:15am and leave at 4:00pm so I have hours to play with Amy when I get home. She goes to bed at 9pm and gets up at 9:00am every day and we have always done her meals/sleeping around me having maximum time with her at night. We eat dinner at 5:15 when I get home as a family and that is great. Occasionally I have to work late but it is rare. But, I want out of work and we have a 5 year plan for me to retire. We are working on a couple of business ideas which we will implement over the next 5 years then we are moving to the country...way out so Amy can go to a country school. Maybe you could work on your next business idea, and keep doing the one you are doing. Hang in there, it is tough but hopefully it is not forever.
