Would you let a 3.5 yr old sleep on the top bunk of a bunk bed?

So we have rails that you can install on the sides for our son. They don’t recommend under the age of 5 I believe.

Hard no

How big is your MIL? She can’t sleep with the baby on the bottom bed? Having the baby sleep on the top is very dangerous, in my opinion you shouldn’t allow it

I researched this for my 3.5 year old. There are bunk beds specifically for toddlers that are very low. Anything other than that is a no for me.

With that being said I know a family that have their toddlers in bunk beds and it’s working out 🤷🏿‍♀️

Not worth the risk

Yeah. My kids have a bunk bed. It's designed for toddlers and my son is the same age and he sleeps up top. It's low to the ground and has rails all the way around it. So he can't roll off the stairs are not a ladder but actually stairs

I think MIL can climb up there instead 😆

No I fell off one at 4 on holiday, went between the wooden slats on the side 🫣

My son started sleeping on the top when we moved in May of 2025. The bunk bed I just posted my son can't roll off of it. He moves around in his sleep all night long but has yet to even get close to falling off. He was almost 3 when he started to sleep in the top. He turned 3 in June

It really depends on the bunk bed. I would probably say no this instance regardless of the bed because it is more of a trip thing and you don't have time to train how to use it. We got a (homemade) bunk bed when my oldest was around 3.5. the top bunk is only 4ft high. We spend a good week working on going up and down the stairs, safely, not jumping plus going over safety rules like dont play with others while using the stairs or they are using the stairs, we sit on the top bunk, dont throw things off the bunk, etc. since this is more of a visit thing, you won't have time to do that.
Also, it's not just about them sleeping up there ..the hardest part is of they wake in the middle of the night and try to navigate the steps half asleep.
