There are many posts on this topic if you want to do a search you will find some interesting threads. My boys are 19 months apart (would have been 20 but DS2 was early), so much as the same as the gap you'll have. It is very normal to worry that baby 1 will miss out when baby 2 arrives. I know I was. But in my experience, that is not the case. DS1 has coped very well with the arrival of DS2, they have been the best of friends since day 1. Whatever they each miss out on by sharing parents, they make up for by having each other.

Some days with 2 under 2 can be hard, but overall I love it and it works well for all of us. The best advice I can give you is to prepare Blake for the fact that a new baby is coming, and also for the fact that mummy will be going away for a little while when the baby comes. Then just enjoy!!
