DS2 is currently 2.4 and will be 3 (exactly) when the new baby arrives.
I don't mind tandem feeding if we end up doing that but I am not keen on the idea of co-sleeping with 2 - DS2 is not especially gentle or relaxed in bed and will climb over me to access the other boob, so it feels like a safety issue.
DH reckons we should make some kind of plan to get it manageable before DC3 arrives, I am a bit oh well, let's just see what happens, he might be sleeping through by then (DS1 was). But I might be being a bit too laid back 
Any experiences? If this was you what did you do (if anything) and did you regret it or did it go OK?
