Is this a really bad idea?

[Youngfrankenstein]

My daughters are 6 years and 13 months.  Right now they each have their own room.  The goal is, when the LO starting sleeping okay at night, we'd combine their rooms like their brothers.  Well we've reached 13 months and my baby is a terrible sleeper.  I am at my wit's end with her at night sometimes.  I used to be able to rock her back to sleep instead of nursing her back to sleep each time she woke, but now that is making her really angry. 

My point/question is, would it be stupid to put her in a daybed with a rail?  I know she is very young, but I feel my older daughter would sleep through most disturbances in the same room but having a bed I can lay next to the baby in would be nice at times.  We bring her in bed with us sometimes when I just can't be up anymore but it's only a double and no one sleeps very well this crowded.

That plan was that when we combined rooms, we'd buy the girls these matching day beds from Ikea and such.  It that just a bad idea?  What about putting the baby on the trundle that pulls out from under the day bed?

I'm just looking for help and ideas.

Here are the beds-they each have a pull out if you buy another mattress.

Those are adorable.  Honestly, I don't see any harm in trying.  If it doesn't work, you can always wait to combine rooms a little while longer.  My ds stopped falling out of the bed (he rarely did anyway, and my bed is so low to the ground that it doesn't matter when he did) around 18mo, so I don't think theres anything wrong with a daybed with a rail.

My only issue would be that instead of just rolling or falling off a mattress on the floor she would topple over the sides of the daybed making the fall worse. I would put a mattress on the floor and then you can lay on it and if she ventures off will be safe (child proof the room).

As long as she knows how to climb down I don't see the problem. My girls have a trundle bed type thing but its not close to the ground like a lot of trundle beds, I could easily fit those drawers under. We have a guardrail (actually the bed came with rails on both the top bed and the trundle) and taught both girls to climb safely on and off the beds without climbing onto the other one (they switch who wants to sleep on the bottom and top at times. Eventually when DD1 is a little older I'm going to get a bunk bed but at not quite 4 I worry about her not climbing safely down if she has a bad dream and tries to come find me.

What does your 6 year old think about the idea? She might have an opinion about it, you will be surprised what kids can come up with (my oldest just surprised me by asking when i plan on putting a bed in their room for the baby.. who's not even born).
