Has anyone used one of these while co-sleeping ?

I think its fine to co-sleep. we didnt have room for a crib in our 1 bedroom apt so from day one our daughter has slept in our bed. at first it was just me and her and my boyfriend would sleep on the couch cuz he felt more comfortable. when she was 3 weeks my mom got us that little co-sleeper bed thing and we absolutely LOVED it. seriously its so convenient. i didnt worry about her rolling or anything like that. she just slept in her little bed next to me on the bed. we used it until she no longer wanted to sleep on it. around 4 or 5 months, i cant remember exactly, she wouldnt use it anymore because it was stiff and she would only sleep on soft cushion. so she started sleeping with us in the bed, now shes almost 9 months and the three of us continue to sleep together with her in the middle. but anyway i just think co sleeping with a newborn makes everything a whole lot easier and this little bed took our only worries about co sleeping away.
