15 weeks baby rolls on her belly. How to make it safe for the night?

[SunnySideUp2020]

Really need help here.
Our first baby, she is very active and started rolling all the time from back to front this week. But doesnt know how to roll from tummy to back, so when she gets tired she struggles and face plants.

We are currently on holiday and she doesnt like her travel cot so she co sleeps with me.
The bed is very firm and cannot fall out onto sides but finding her struggling on her belly at 5am today almost gave me a heart attack.

How do I make it safe? Hellllppppppp please

All tips welcomed.
I can even buy a new cot for the 2 weeks or whatever but i just dont know what is the solution?
We are going to train her to roll back but i know it is not an instant solution.

If she can roll, then she can turn her head while lying on her front.

That means that she is safe. Cros,, because she wants to roll back, but not in danger.

The danger from front sleeping is because they don't have the neck strength to lift their face/tuen their head when they are face down and can therefore suffocate. For your baby, if she is face down and her face is covered in sheet/matress, she can turn her head.

So at the moment when she if stuck on her tummy she will eventually cry from frustration and you wake up and turn her back.

It will only be a few days/weeks before she can turn herself back.
