I would sit my MOM down and explain about baby proofing the childs room....it's not just about protecting MOM's fragile things but what the hell is more important then protecting her GRANDCHILD...
Next time you are out buy the house enough of those baby proofing thingies for the elec. sockets and install them.
If Mom still objects to them....call upon her close friends or relatives to TALK some sense into her and as she pulls them out...YOU put them back in and be firm about it.
I tend to think until the childs room is completely safe for her....it would be safer for her to stay with the crib...at least she's not yet climbing out of it and at least until she reaches that stage, she's safe while in her room.
My heart goes out to you with facing back surgery. I too have a back from hell and was told I need surgery. My attitude about it was and still is....maybe in my next life. I've been told it's a painful and long recovery process and may not be successful. So after I finished my physical therapy process, ((((learning how and how not to use my back)))) I found a Pilates studio that has Pilates machines and a great instructor...my physical therapist and pilates instructor talked and I signed myself up for 2 classes a week. They started me off slow and now 4 years later I'm doing level 3 and 4 exercises. I can now even do some of the same exercises without the machines on a mat. I'm not saying these gentle exercises cured me or would work for everyone, but along with pacing my physical chores and going to class... it's REAR now when my back hurts. The exercises have made my mussels strong enough to protect my back...not to mention it has corrected my posture. If you like, Google "Pilates" to read more about it...especially about the history of it and "John Pilates" who invented it along with the machines he built to make the exercises pleasant and easier to do.
In terms of your little girl's fuss about bed time, know little ones go through so many stages and it all takes alot of patience without back pain so you must be finding this so hard.
Does she take a nap that's to close to her bed time?? Or maybe she's to active and excited right before her bed time??? Make sure she's not eating stuff with suger in it before bed time....
Among all the things you have tired to settle her down at bed time, have you tried staying in the room with her until she actually falls asleep??? Maybe move a chair close enough to the crib for your comfort...put her in and hold her hand,or pat her and talk softly to her...let her know you are there or maybe even hold her in your arms until she falls asleep before putting her into the crib. I don't think it's a good idea that once you put her into the crib, she should be taken out again...
I have friends who take their little one for a car ride right before bed time which knocks him out for the night....So I tend to think it's the movement or the sound of the motor that does it for him. Maybe try rocking her and playing either some soft music or some talk program on a radio.
