There are 2 scenarios here. First, one of my current SB's got pregnant by her BF last December. Once she decided to keep it I shifted from SD to supportive friend while she tried to figure out to proceed with an unsupportive BF (he tried REALL hard to get her not to have it) and a dysfunctional family. I have bought her a few baby items, and an occasional $50 for gas, but no BCD's and no allowance. She is due in 2 days. I shall not be present nor shall I visit her in the hospital. Still not sure what I will do if/when she wants to bring the kid to my place.
Next, there are new POT's who mention they are preggers in their profile. There was one Preggers POT in my area last year. Twenty-three, half Asiam half white, quite pretty and about 4 months along.
We messaged a few times before moving to text. By text she was DTF for a reasonable allowance. She lived reasonably close and agreed to a M&G. Confirmed the day before. The day of confirmed again in the morning but no reply. And no show.
About 2 months later her profile popped up again. I messaged by text but no reply.
To address your question head on, I would approach this like any other arrangement, with a few exceptions. I'd make it clear that I am not going to be around for anything like child support after. And I'd make it clear that I am not available for non-date activities like rides to a doctor, shopping for baby stuff, etc. And I'm guessing I'd politely move on once she got to around the end of the 8th month.
Here's a fun exercise: Clear all of your search filters except location and radius. The search for keyword "pregnant" or "preggers"
Prior to the new AI-Cop system, I could usually see about 4-10 profiles within greater LA (50 miles). Today, I see 9, but some have been inactive for far longer than 9 months.
