Trill and Arimeh - when you moved the older ones out of the cot to make way for the new baby, how did they cope? DD will be 22months when the next bub arrives, and the plan was to move her into a bed and then the cot will be free. But did you do it a while before the new bub came along, or when bub came home from hospital? I;m just worried about whether she'll get jealous about losing her bed to the baby.
The Erin and Paige were 3mths old when they needed the cot, so there was enough time to get Lindsay, and then Erin used to the idea of being in the bed and not the cot. We already had the beds set up and they were using them for day sleeps for 2-ish mths before the final move. Luckily it was never an issue for us, but we've had friends who ended up getting a second cot on loan for a little while.

Jac, I think Alister will be at least that old before he moves out of the cot too LOL, so you wont be the only one.
