It's true, people really do think that the SAHM thing is not as much work as it is unless they have done it. I often catch the (ooops) remarks from parents that work which imply that I have it so easy compared to them.
I worked for two months after my maternity leave with my first. SO, I can compare the two. I'd take her to day care, I would go to work, hubby would go to work, one of us would pick her up, and come home to a house that was clean.....no one had been there all day!
I had extra money to order in take-out or go out, to bring my nice professional clothes to the dry cleaners, and even some of my casual clothes. (everything in my life is wash'n'wear now LOL!) She was at the day care long enough in a day, so I could fit in a dentist apt, a work out, to pick up the groceries, buy diapers run errands. When I came home, either I had to take her, skip it, or go during the hours I should be sleeping.
I had 2 15 minute-a-day and a 1/2 an hour lunch breaks with my work.....there are no breaks as a SAHM.
On sleep...my hubby and I would alternate getting up with her at night, so we would each get one night of full sleep every other night, but when I came home, I became the one who got up every night, so he could make up for our lost income at work.
Socially, when I worked, I talked to adults about complex interresting issues all day. When I came home, I would crave uninterrupted grown-up conversation about grown-up issues. I could meet with other moms, but really, my attention needed to be constantly on her (and soon after our 2nd, then 3rd child).
If I was sick, I took a day off from work (paid!), while she went to day care. When you are a SAHM, you still keep working when you get sick.
And here is the weird thing. WHEN YOU ARE A NEW MOM, WHO WORKS, people offer to help out, babysit, cook a meal. When you come home, and need a break, no one offers anymore, they figure you have it made and life is easy...just hanging out playing with your kids.
From experience, I can say, being a SAHM is more exhausting physically and often emotionally than it was as a working parent. BUT spiritually and maternally, it far outweighed anything I ever gained from my job.
I will never regret that I came home, and I will never have that chance again, though I can always find a job when the kids grow up and leave.
