I haven't read any of the other replies but think I qualify at answering as I'm nearing the end of my SAHM days.
My feelings are like this...
I have had very strong views about children's foundations being built within the first 5 years of life. I wanted to be home for them, I wanted them out of the institutions until they have to. I thought that my husbands would be the example and the work ethic and I could be the nurturing example IYKWIM.
I still feel this way...I really really do...
Reality has hit me in the face and I'm now facing trying to get back into the workforce with absolutely zero education and formal experience. My own mother has faced this also...she can't even be a grandma because she's slogging her guts out in a menial job so that she can build her super...she also needs to still pay her bills and 'live' on such a small wage. She was a SAHM for years also...she's now paying for it - big time!
Although I still feel the same way I did then...I do kick myself that I didn't at least do SOMETHING during those years...be it part time work or part time study between kids. I could have done it...and I didn't. Now I face about 4 years of study before I can even do anything of any value workwise! Sure I could become a cleaner or a check out chick...but sorry...no I don't see myself doing that till I retire! I want a career and I only wish that I had been working on this career all this time.
7 years ago my ex left me for another woman and left me a single mum of 4 children with no money, nor prospects, no means to support myself - nothing! It was that moment that I realised, as wonderful being a SAHM was, the harsh reality is that being a SAHM is a dead end. It really is.
I don't believe that I was a bad example however...but I do believe my girls see and I have told them that being a full time SAHM, although it is very admirable and important, in the grand scheme of things really isn't a good idea as reality, as it stands, isn't set up for us mums who have been out of the workforce for so long with little or no superannuation etc
So if anyone was going to ask me my opinion I would say...don't do it FULL TIME. At least be doing something in between, either part time work or study...anything! Because you don't know what's around the corner.
