We started co-sleeping with our son at first wake at around 8 months, and have been doing that continuously for the past 7 months or so (basically he sleeps with us in bed between 2 and 6ish AM). I've enjoyed the arrangement but my wife is tired of it, due to getting kicked and punched all night long. On top of that, she's 32 weeks pregnant and really needs the sleep.
Does your wife share your enthusiasm for co-sleeping?
