I've been a single parent since my husband died (car crash) when our youngest was just a year old. She's now 9, so I've had time to develop my single mom mojo. Some days are pretty successful; others are simply an exercise in multiple displays of plate spinning. My life is a lot more manageable now that my kids are older and more self sufficient, the early years were pretty damn tough with running from day care to elementary to high school to work and lather, rinse, repeat.
My eldest (actually my husband's daughter from his first marriage) is pretty well launched into young adulthood. She graduated from art school last year and lives independently with 3 part time jobs. I still have her on our health plan - thank you ACA, and pay her cell phone. The kids have always had chores and responsibilities, most especially taking care of their own personal "stuff" and helping with basic home upkeep. We live on 2.5 acres and have a vegetable garden in the summer, pets, so there's always a lot to do. I tease them along with this with lots of "carrots", which include screen time and then something fun each weekend, like a movie with friends, pizza, etc. My youngest two are currently involved in swim team (DS) and horseback lessons (DD). Never is there more than one organized activity at one time, and they go to a variety of day camps/sleepover camps each summer.
My finances are in decent shape, thanks to the small life insurance I received, and the Social Security Survivors' benefits my children are eligible for. I own a small business, and have ventured into a duplex rental with my cousins. We've also done a couple of real estate flips, the last of which I parlayed into a very small commercial space for my little company.
This thread is helpful, I like hearing how other single parents are managing in a variety of circumstances. I've worked really hard at controlling spending, developing reasonable (admittedly not perfect) saving patterns and looking toward the future. At 39, I won't be retiring any time remotely soon, but hopefully will be well before the American norm of 65 or so.
Sending support to everyone else out there whether you're new to your single parent gig or a grizzled veteran of the trenches like me :)
