I'm a tad bit nervous to post here. I have 4 children ages 7, almost 6, almost 3 and 1. Are you all having panic attacks yet?

I'm on the other side of the fence (obviously) and have a few friends without children. I don't understand their decision but support it and don't judge it. I think from a lot of the posts I've been reading, people without children are judged by people with children and vice versa.
Being a mom is the most challenging spiritual journey I've ever been on. I have always been quite fond of personal growth and self-discovery and this parenthood thing tops them all. It is even more of a struggle because there is nothing tangible to put your finger on. It's not about meditating or doing yoga or walking in nature. It's about raising children to be self-sufficient, decent members of society. It's about getting your buttons pushed and learning to manage your own reactions, etc. I could go on and on ....
But, why did I want children in the first place? I loved children as a child. I worked at camps. I always helped the underdogs or the struggling children. I believe it was something innate within me. I wanted to work with children and spent my professional career working with abused children. Now taking care of my own four children is more "difficult" than dealing with the emotionally disturbed children in the residential treatment center.
But, I still want them in my life. Hmmm... why? I think part of it is tied to G-d. If I did not have my children - oh, the freedom, the travel, the less financial stress- but those are external things to me and raising children provides something internally.
I left work before we had our first child and my husband was actually out of work during two of the births of our children. Yes, it was stressful, but it was just a part of life we had to deal with. We live for our children, not our retirement, so we don't spend a lot of energy stressing about that.
I hope this provides a little insight. If my words are too wishy washy, I'm happy to say more. I didn't want to go on too much.
Thanks for letting me be here.
