I've seriously tried at least a dozen times with 2 different women and 2 different men and they just WON'T have babies...is it a glitch or is it just harder in vv4 than it was in the other ones??

If the villager is not a adept/master at parenting, this will take several attemts to have a baby. Just spam-drop villager, until the baby will be appear in female's hands or you will see counter of villagers increased.

I have..I think 3 out of 4 of them are "adept" at parenting....i'll keep trying

Thanks!

Also, I am not sure about this, but I think you should have a "private" hut(with flowerers and stuff) already built. This one builds very quickly, so you shouldn't have any problems with that.

Yep..did that first. I'm also working on the other hut just in case its a "housing" issue

it took about 30 times but we finally have a baby!! =) Now I can stop worrying

Well, think about the good that came out of this; your villagers now have gained lots of experience in parenting.

Come to my village Amber. I have a 67 year with a baby!
(No event by the way, just in case there are events where this could happen.)

There are events that could cause that, but they aren't necessarily the reason an older female villager is nursing a baby. VV4 is different from VV2 and VV3, and there is no longer an arbitrary age limit for producing children. It is less likely, but still possible, for older villagers to add to the tribe.

Once my female scholars hit 50+, I put them on Parenting in the hope they can teach some of the younger men how to parent.

In this case, my female was 60+, I put her on Parenting and exited the game only to come back and see her carrying a baby...

There was no event or time travel involved...

It doesn't really worry me, I just thought you might need to know .
