So many mothers from all walks of life have been told, "Enjoy them being little, you will miss it one day." Or something along those lines. The truth is, they are right.

Brené Brown (author and researcher at the University of Houston) defines shame as, "an intensely painful feeling or experience of believing that we are flawed and something we've done or failed to do makes us unworthy."

Mom shaming is common among mothers themselves. Mom groups on Facebook are a direct example of that. What happens is people criticize a mother for making parenting choices that differ from the choices they have made or would make themselves. Moms in their 40s have been through too much already to parent by other people's standards.

Moms have a lot going on. When it comes to remembering everything, sometimes it just doesn't happen. A study done by the University of British Columbia shows that motherhood has a permanent impact on your cognitive function. So basically, "mom brain" is a real thing.

Stacey Rosenfeld, Ph. D, says by the time women get to their 40s, they've [hopefully] given up the notion that happiness exists within a certain shape or size.

Not only is sleep beneficial, and healthy, after all the sleep moms lose in the early years, being able to finally get some sleep feels so good. However, sleep changes after 40. According to sleep doctor Michael Breus hormones have a lot to do with it. You go to bed exhausted but still have trouble falling asleep. You wake at least once or twice a night—sometimes to go to the bathroom, sometimes just because. Often, you don't sleep all the way to dawn, waking way ahead of your alarm, wishing you could grab that extra 45 minutes or hour of rest. Welcome to sleep in middle age.

Most moms in their 40s are good with being in bed by 9 pm. There is nothing wrong with enjoying a night out occasionally, but alone time is a good time. Mothers over 40 don't mind being alone. It often allows them time to get back to things they liked to do prior to having kids. They absorb more of their surroundings and get to know themselves again. It can be empowering.

Moms in their 40s tend to be more seasoned. Most don't feel the need to always be perfect or to judge other moms for how they choose to raise their kids.

Moms sometimes lose friendships after having children. Their lives tend to be focused on their kids and priorities change. Not all friendships can last through this. It may be hard to go through at the time, but when moms get into their 40s, they no longer focus on quantity, but the quality of friendships. Those that stuck by her while she was raising her children, the ones who would drop everything at a moment's notice to comfort her. Those are the kind of true friendships strived for by moms in their 40s.

Moms in their 40s tend not to care as much about what others think about them. They know who they are, and they know the people they surround themselves with. Hearing what someone may or may not have said about them or someone they know doesn't light the same match it used to.
