I thought about a cot bumper for flynn but then read somewhere that the are not recommended once kids can stand up cause they will use them as footholds to climb out of the cot.
DH is adamant we need them too, but this is exaclty why I'm not keen.

so we're going to try for his own big bed.. and he'll probably have pillows beside him like he has in our bed and it'll be easier to tuck him in in a bed than a cot. We'll see how we go. I think being so mobile it's not a problem. I think SIDS is only a real risk up to 6 months or so.
That's exactly what another friend of mine suggested - a big bed. Her son only fell out a couple of times and then figured it out - stopped him banging his head.
