Hugs lovely. Like kelebek, all I can do is offer understanding and support. DD2 was a shocking sleeper and with DD1 still tiny I had to just let her survive on cat naps or sleeping on me because I just couldn't devote the hour + I needed each and every time she needed a sleep during the day. Up until 5 months when I stopped breastfeeding she would feed for up to 45 minutes a feed, with maybe only 30 minutes between feeds so the only way I could survive was to co-sleep with her. As soon as she woke I could throw her on the boob and try to hopefully snooze off again while she was feeding. Not ideal, but it gave me a little sleep at night so I was better equipped to battle the days. I did try on a couple of occasions to let her cry it out - purely because I felt so torn between either abandoning one of my daughters or the other - but the only thing that achieved was that we were all hysterical.
Your plan sounds like a lovely, gentle way to try and get him to sleep to me, but if he's not responding to it anymore then I'm not sure what to suggest. Normally I would say can you put him in a sling or carrier, but given his weight that might be out of the question for you for any real length of time.
Sorry your CHN is being very unhelpful. I really don't understand how there seem to be so many in the community who are so completely unsupportive of mums.
