We cosleep with 6 month old DS in a sidecar cot and are pretty happy with the arrangement - BUT the one fly in the ointment is that I'm wondering if I'll have to night wean and/or move him in order to get my period back?
Currently he feeds at least a couple of times a night, as its taking a while to get the hang of self-soothing and it's by such a long way the easiest sleep inducer 
It is still early days, but it took 2 years of trying (unexplained infertility) and an MC before DS arrived and we'd really like to start the ball rolling with ttc #2!
