Chloe is about 4.5 months old. I have a play pen which has her bed, her food and water, lots of toys and a wee wee tray. She never complains in her pen and that is where she stays when I leave the house. I have a camera above it so I can check on her when I'm gone. I noticed all she does is nap and sometimes she'll play with her toys. When I come back and let her out she gets super excited and runs all around the house and plays with me. My question is when can I leave her home without a play pen? When I shower I leave her out and she just goes to lay in her bed while she waits for me, but I'm just scared to leave her without a pen when I'm really not home

opinions?
