A big barrier to mums getting time to themselves, I have found, are partners who don't take an equal share of childcare, for a number of reasons. Also, families where the parents are separated and so there is either no one to help, or time with children is precious because it's limited.
The ages of my pals children range from older teenagers to toddlers; as kids get older and lead lives of their own their mums will get more free time.
However, for the present, are you lonely, or do you crave a bit of 'adult' time with your girlfriends? Who doesn't.....!?
Do you have any child free pals?
I am child free. Both me and my husband work part time, and I work in a school - but not as a teacher, so get all the holidays to myself. My big gang of best buddies are all mums, though, working mums, single mums, busy mums. I see them loads because I am very flexible and able to fit in seeing them around their schedule - I am also very popular in the school holidays because I love to spend time with their kids and am a keen babysitter!
I also have a very separate gang who are mostly child free, like me, and we all get together often for theatre trips, lunch, outings - get a couple of child free friends and enjoy some time with them!
