Full disclosure:  I have only dabbled in the sugar bowl.  I've had one SB that I met with a couple of times.  But, never managed to get BCD.  And now, several POTS with whom I have exchanged messages on SD.  What do they all have in common?  They all profess to be single mothers.

 
As it turns out, in every case, their single motherhood makes it difficult to schedule meet-ups of any duration longer than an hour or so.  Certainly not enough time for any meaningful BCD.

 
Which led me to wonder, is it a scam?  Have some of the POTs figured out that the solo mommy persona is a great way to keep a guy interested, maybe inspire some sympathy and extract a little 'assistance', while minimizing the expectations.

 
Just wondering whether I'm the only one experiencing this phenomenon.

... there are additional factors to consider when sugar-dating a single mother as a POT.

 
First, and I cannot stress this too much, her kid(s) will ALWAYS be her top priority. And that is as it should be.  Beware the POT who prioritizes anyone or anything over children. Those POT's should be avoided, unless you don't mind being interviewed by CPS as a witness.  

There will also be scheduling issues, as childcare will again take priority.  But that's not necessarily a fatal flaw, especially if you plan in advance.    

 
Next, understand that she will be much more interested in cash than bling, because kids are expensive. This may be a positive, as she's not likely to ask for a $4k Dior handbag. But she may just ask you to pay for her kids food, toys, medical, birthday parties (real life - had a hot Philippina ask me for $350 to cater her kids party with special order lechon. And I was not invited.  And (you probably see this warming up) she ghosted me after the party.  

 
Finally, and this one's important: She has already set a very important precedent:  She's not likely to get an abortion if (when) Daddy gets her preggers. So beware the intentional or unintentional baby trap. This is especially dangerous if her current baby daddy is not around.  

 
I'm not saying stop, just keep your eyes open along with a healthy amount of skepticism.  

 
Life is good

 
The Cat

I've dated several.  One of my best arrangements, was with a single Mom who was beautiful, very enthusiastic, and happy to schedule regular meets every 2 weeks.  For 2 1/2 years!  For a very modest gift$.  She was a sexual dynamo, no holes barred, and super sweet as well.  

It was not my intention to suggest that everyone SB who claims to be a single Mom, was putting on an act.  I sincerely believe that there are single Mom SBs our there.  I know for a fact that my one and only SB was a single Mom (she had their names tattooed on her).

 
But, most successful scams are based on truth.  My cynical side simply realized that it could be an excellent cover story, depending on the type of SD you wanted.

I have been seeing one on and off since 2018. She got knocked up by her BF who is out of the picture now. I don't think he provides any financial support. Her baby boy is only 2 months old. She is in her mid-thirties. I go to her apartment. She puts her baby to sleep and then we do our thing. The baby sleeps soundly for several hours so I don't feel any time pressure. I do send her some extra money once in a while so she can buy stuff for her baby. The other single moms I met either have teen-age children or get a babysitter so they can usually stay with me for several hours without having to worry about their children.

Many SB's will elicit sympathy attempts.  I presume single moms more so.  I assume by scam you mean they aren't actually mothers at all.  I don't really think being a single mother increases their market value, so it would seem counter-productive as the basis of faking it.  But that's just my opinion.
.
That said, the marriage rate is near historic lows and single motherhood is near historic highs.  So expect to see a continuation of the availability of single women and single mothers on sugar sites.

A couple of weeks ago I hooked up with a SB who during our meet told me she was a single mom, and in fact, recently gave birth.  She was still nursing and actually suggested I taste her milk.  Never did that before.  It was so flavorless that I couldn't tell if I actually got any.  But she squeeze her nipple with her fingers to show it squirt out.   Anyhow, that's off my bucket list. haha

Forgot the marriage rate graph (rate of marriage for unmarried women.)

And single motherhood by race

That’s either you TOFTT, or TMI, or both.
