Oh the trundle is an excellent idea! Will try and remember that!

We didn't buy the convertible cot, simply because we'll need the cot for #2, and figured it'd be more fun to take DS shopping for his big boy bed, than to go and get a new cot for the bub.

I don't think a single will be overwhelming for him, coz he's slept with us so often. In fact if it wasn't for him crawling off the edge of it.. I'd consider putting him in a bed now! He sleeps so much better on our bed than in his cot.

I'm the same with the TT - we plan to go straight to the loo, rather than potty to loo. I reckon the less transitions the better too. hehe.
