Ikea cot as a co-sleeper / side-car?

[theclockticksslowly]

It's just me and one year old DD and up to now we've co-slept (didn't intend to but she sleeps well, I sleep well like that). I currently have a bed rail up on her side which stops her rolling off but now she's more mobile and eager to explore I'm starting to think its getting unsafe. So looking for options.

Clearly I could just get a crib and be done with it but I'd prefer to continue to co sleep. Perhaps I'm making a rod for my own back but she sleeps so well like this.

I am considering side car-ing a crib so she has her own space protected on three sides (I'd be the barrier on the fourth). I'd be interested to hear tips from anyone who has done this? Budget is low but I hear the ikea cribs get good reviews. Are they all suitable for this?

Ideally I'd put the crib between the wall and the bed but that isn't possible although the crib could go between the bed and a heavy bedside table perhaps.

Have questions over the height of the crib base and the bed. If anyone has used an ikea crib would you mind measuring the height from the floor of the different base options?

Any suggestions much appreciated!
