my son will be 2 years and nearly 3 months when I pop in the next few weeks, we have done nothing different except he knows there is a baby in mummy's tummy. We have left him with his dummy and let him stay in his room and his cot until we see how he goes with the new arrival and after a few months will shift him down to the other room and into the big boy bed, we bought a bedside bassinette for now. I didn't want to cause too much change for him as he is not as mature as a lot of other kids his age. I will let you know in a month or two! congrats on your new bub!
