This is the ex-pen I used for my girls until they became more potty trained. You can get extra panels to make it bigger, and can keep their crates in there, beds, potty pads, food & water.

It is light weight and easy to move. I loved having it to take out on the lawn or patio to keep them safe when I was outside. Also great to have a safe place to put them when they were little if company came over and there was danger of getting stepped on.

Now that my girls are all grown up, I use 2 panels of the pen as a gate inside the front entry so they don't dart out the door.

NO never. At first I WAS paranoid because she was SO little, if I would feel her moving around, I would just get up and take her out. Maybe 2 am or 4 am........but NEVER wet the bed. Like I had mentioned, They do sleep in the snuggle sacs I made them from little on so I always know where they are. They liked to crawl UNDER the blankets by our feet and that's a no no, SO now they stay put allllllllll night in the snuggle sacs. Maybe you'd like to check out my snuggle sacs on my website? :):animal-pa

My Molly has her own bedroom. It's just me and my husband and no children so we had the extra room. When we first got her she slept in my room in her crate but she was wearing me out getting up every 2 hours to potty. So...since she was doing very well using her pee pads we thought she might like her own room. She has more room to roam and play especially since the both of us work days. This way she's not confined to a very small space. Her crate is in there for her to sleep in and her food/water bowls and plenty of toys. :) We just recently put a small heater in there to keep in warmer at night for her. I was worried that the electric heat we are accustomed to might not be enough for her cause it seems to be a little chilly in there. Not now though. The secondary heat works perfect and I only use it at night. I don't want to leave it on during the day when I can't supervise. She seems to do fine in her own room. When I'm home though she stays out with me. She can come and go to her room as she pleases. And she does when she wants different toys or food or water. :) The only thing is I can't seem to get her to go night night on her own. I have to carry her to the crate and put her in myself. I could use some advice on how to get her to go to bed in her own when she's ready. Right now she stays in my lap till I put her in the crate. Good luck in whatever you choose to do for your baby.

I have own room, playpen, and xpen....I use them all and I make sure I do...because life changes all the time! I want them to be use to everything.

I couldn't agree more.!
