sure!

I think I was 4 and my brother was 5 when my parents got us a bunkbed.

As long as they're not going to roll out of it, or jump off it, or do anything dangerous on it to injure themselves, it should be fine

I would put them in a bunk bed around 6 or 7 .but as long as you know the one on the top part won't fall out it should be fine :] good luck!

around the age of 4 for the bottom bunk and a little older for the top bunk. I used to have them when I was a kid. I was older so I got the top until my brother was old enough and we knew he wouldn't wiggle off the bed. And that he could climb on the ladder well.

Its okay
they wont get super hurt like off the building hurt
theyre kids they like to have fun

My 4 and 3 year old sons have had bunk beds for almost 2 years. They do really good with it and on occasion have been known to turn the bottom bunk into a secret fort. Just make sure that the bunk bed you get has a good safety rail on top and they should be fine.

usually bunkbed manufactures recommend that the top bunk not be used by a child under 6... but i have seen many many kids use them before 6.

My 4 and 7 yr old are currently in bunk beds.. so I think it should be fine for you

I would wait until they are a little older. kids have a tendency to roll off the bed. Or you can buy the bunk bed and make it twin beds until they are older.

yeah ask them and make sure it is properly assembled

When they don't pee in their beds. I would feel very sorry for the person on the bottom if it was not the case.

My boys have a set of bunk beds. My 8 yr old is on top, the 6 yr old on bottom. We've set a tentative age at 8 for the older, just because he wants to know how old he has to be before he can sleep on top. However, we feel that we will know best when he is ready (i.e. does roll out of bed....it's uncommon of him to do it, but still happens often enough for concern). My largest concern would be them jumping off of the top which my youngest wanted to do at first. He knows better now though.
I know I'm probably over cautious, but my Mom's friend's son fell off of the top bunk (years ago) hit his head, and died. You just can't be too careful, you know?

We have bunk beds for our girls that separate into 2 separate beds (how they are now) and intructions/recommendation it has is 6 y/o for the top bunk.

I think it really depends on your child though, if you think they are ready. My kids are 6 and 3 and the 6 y/o does not want to be that high up yet. However next year we are moving and they will have to share a room and use them as bunk beds, so she'll have to then.

I think the 5 year old would be ok on the top bunk, but be sure that there is a rail, just in case. You can also buy bunk beds with stairs instead of ladders, which is much safer.
