My kids are 8, 5 and 0.5 years! We talked a lot about 'our' baby so that the kids felt included and a sense of family belonging rather than feeling displaced by the new arrival. It has worked well for us and a new baby in the house has always been a joy for the whole family. My big kids are quite a bit older than Miss P and they are very helpful and responsible with her. I love seeing her face light up when she sees her brother or her sister and I love it (both practically and emotionally) that either of the big kids can settle Miss P if she's grizzly.
