I liked my fixed-side cot.

For one, DS can drop down the side of my mum's drop-down cot (after just a couple of weeks in it age just under 2!).

Also, he likes pulling himself up on the side. I like sitting on the fixed rail as I lean over and sing DS to sleep. Sure it's easier now he's in a bed but he's not about to fall out of bed as much now. I also liked the fact that it could double as a playpen if I needed it to.

THB, moving the rail up and down on my mum's cot annoyed me so I left it up all the time. Too much bother to move down when you have a baby in your arms asleep.
