DS 14 months old wont sleep unless rocked. We have two options let him cry for an hour or I rock him for an hour cause DH can't physically rock him due to Severe chronic hip and knee problems. I don't mind the cuddles but I am in so much pain by time he is even starting to close his eyes I cannot do it every single time he needs to sleep anymore. Nap time and bed time both need to be rocked unless taken out in the car. He no longer breastfeeds, doesn't have a dummy, doesn't have any physical comforter like a blanket or teddy so is solely dependent on the rocking. If we try being in the room without holding him he gets worse. If we try coming back in after stretches of time he just gets worse each time we leave. We need help because this past week it's been every night of over 40 mins of rocking or if I've left the room to cry myself due to exhaustion or pain from rocking him for so long he'll just cry for over 40 mins. Any advice experiences help would be greatly appreciated thanks in advance.
