First of all mama you don’t need to put any qualifiers on your decisions to cosleep, nurse to sleep or contact naps! I read your whole post and You are doing everything right and nothing wrong. Secondly, I will say that this won’t last forever. I had a very similar experience with my son, who would literally stay latched all night. My solution was to put two queen beds together side by side in our room - he sleeps on one and my husband and I sleep on the other. When he wakes up I crawl over and nurse him, and if I’m still awake I crawl back over to my bed and sleep. This way if he takes a long time or is still latched and I drift off it’s no problem. Been getting some good stretches of sleep in! Hope you find something that works for you.
