I had both of these!! the beach tent was really nice-just make sure to check as it can get stuffy in there.Before DS6 was born, my first baby purchase was an older pack n play from an auction (for $1). I used it in my barn. I pulled a sheet over it when not in use to keep it less-dirty. When I did barn chores I put him in the playpen. It worked out great. I didn't use it in winter though!
Another SS-specific baby purchase was I got a little baby beach tent for my garden to keep him out of the dirt and sun. That one was definitely worth it. I used in in winter power outage - set it up in the living room, put blankets over it, put a dog and cat in it to warm it up for kids. I pulled it out in January to break up the monotony. Until it broke It lasted 5 years, not bad.

I had a friend at work, he let the 4week old baby sleep on his chest on the sofa, well he to fell asleep and when he woke up the baby had stopped breathing and died---
