My DD will be 19 1/2 months by the time DD#2 is born...I want to put #2 in the crib #1 is sleeping in now. What options can anyone please suggest for where DD#1 can sleep? Is a toddler bed a good idea? ( I feel like she will fall out) Also, I am moving overseas soon afterwards and was planning to buy the toddler bed then, so is there anywhere else besides the hard floor she can sleep?!

I did look into the arms reach co-sleeper but it won't fit our new bed when we move so I don't want to buy it and use it only for 2-3 months and then have to throw it away.

Thanks.
