Having a third was a huge decision for us. I replied to this thread when I was only half way through my 3rd pregnancy, now DS2 is 9 months old and we don't regret it for a moment. He is an absolute blessing and fits into our family perfectly. Life is a little harder and sleep is seriously lacking, but we are loving every minute of it. We do have an almost 5 year gap between #2 and #3, so the older 2 are very helpful. I have found it has been a great learning curve for them. They have learnt to be considerate of others (and volume control when bubba is sleeping) and being a little less selfish - as mummy just can't do everything for them anymore. But my greatest joy is seeing how they interact with their baby brother and making him laugh - it absolutely melts my heart. 100% worth it!!!
