Cote, anyone who I have told that ds and I co sleep and breastfeed during the night has kept their shock to themselves, that's of course if any of them have even been shocked.
It is ds's norm, and he and I don't really care if it is considered the norm or not. Like you said yourself, it is great that we have found an arrangement that we are all happy with.
FAQ - sometimes on nights when ds has come through to me, rather than me to him, I have woken up in the morning to find him latched on and I have no idea how long he has been there! So I can identify with your friend!
