Hello,
The Playpen is available with the Gold Edition of the Aurora Skies world, however the baby swing is an item as part of the 'Fun for All Ages' compilation. The Playpen item is also part of the 'Tiny Prodigies Early Learning Center' set, which is also available from TheSims3.com store.
Here are the links for the two separate items you mentioned:
Solace Snugabunny Deluxe Baby Swing
Head Start Playpen
And here are the links to the two sets that contain the items mentioned (which are better value for SimPoints):
Fun for Kids of All Ages Compilation
Tiny Prodigies Early Learning Center
I hope this helps and keep simming,
Cody
