Restless SAHM seeks contentment

Once in a awhile I come across a fellow stay at home mom who wants to stay at home with the children until they are grown. After they start preschool, after they start kindergarten, after they start walking, or taking the bus home from school, after they start driving, basically until they leave the nest. That's when I think to myself " Wow she has found true contentment with being a SAHM...I have not, but desperately want to.

It's been approximately 3 years, 3months since I went on maternity leave never to return, and I can honestly say it was one of the happiest days of my life probably because I HATED my job.
Although I loved my coworkers, and the hours were good it was both emotionally and physically draining. So you would think after 3 years, 3 months, and two children later I would be content with my full time position as Mommy. Instead I long for a hobby( preferably on that pays), and continually plan my future career "after all the children are in kindergarten".

We are planning to have a third child, and want Moo moo to be about three. So then conceivably (no pun intended) I will be a SAHM for another 7 years...hmmm...like it or not contentment here I come!!!
