Thanks for your reply. With my two new peeps, I have been putting them together frequently. They're happy and/or elated, and they've plenty to eat. The missus was a "bit sick ", but I figured out what was ailing her; and didn't try to put them together until she was elated again. If I try to put them together in bed, they are "making the bed". On the couch, they "need to sit down". I've tried to put them on the bed purchased for the children I did have, but then they're "looking for snacks, laundry or something to read. On occasion they've been "waiting for someone", I don't know if that means they're waiting for a wee peep or not. These are the same responses I got with my other peeps, save the first generation. I'll keep trying though, and you'll be the first to know if I'm successful! Sorry I got so wordy...

Austin, I said you'd be the first to know... Cocoa and Rialto had a wee boy peep this morning! Making sure they were fed, fresh and healthy, I put them to bed (though exhausted), and put them together no less than a dozen times until they said they were making a baby. I praised them both and... eureka! Akolo was born--thanks! I never tried putting my peeps together over and over again, one right after the other. Hopefully they'll have a couple more bairns to carry on

Wishes for a lovely day to you! Lisa.
