Anna, I am glad to hear that you are going to keep co-sleeping. I think it is great for mum and bub and in the long run you'll get more sleep that way. I am sure it won't take too long for him to start sleeping for longer stretches.

I think sometimes we get spoilt by our first bubs - Jack was sleeping through from 6 weeks, but Tom was a terrible sleeper for 12 weeks and didn't sleep through regularly until 12 months. I's funny though, Tom has gone on to become a better sleeper than Jack so you never can tell!
