my cousin did something like that and had nothing but trouble.

she ended up having a trecillan nurse stay with them it got so bad.
the nurse said the best patterns of sleep occure when bub is in its own room from day one.

its a personal choice but i thought i would share this with you.
This is the comforted sleep section where many parents find it acceptable and have no trouble having their babies in the same room as them.

I have had the cot set up side car for a couple of months now. Some nights it works very well and others it does not, but that is just my DD, she is not a consistent little girl. For naps I do not find it too much trouble, it is a long way to roll to get to the other side of the bed, but she is big enough now that I don't worry to much as she can get herself of the bed safely if she wakes.
