I think it will be ok, I will use the bed the way it is now and take the sides down later this year, I will also put several paci in his bed, he doesn't really wake up when he misses his paci, but I did have to put a night light on the past week at night, the only thing that put him back to sleep. Walk in/ walk out is something I didn't think about, let's hope we won't have to use it...
Thank you for your help!
