We are having the same dilema. DS has only just started sleeping better at night and i dont really want to move him out of his bed and undo all the work we have done. Plus he LOVES his cot and doesn't sleep well anywhere else. I think at this stage we are going to get the new bub a cradle as they are slightly bigger than a basinette and use that till ds is ready to go to a bed. We figure if we can get 6ish months in the cradle ds will be nearly 2.5 and will prob understand the transition a bit better. Plus DS is such a monkey im afraid that we will have a horrible time getting him to stay in the bed but by that age we might be able to reason with him a bit more.
