I wish i had some magic solution!!!!!
My DD is nearly fourteen months and has coslept since about four months as she just could not sleep on her own. She has gone through periods where we think she is getting closer to sleeping on her own but within one to two weeks she is back to the start again. She is the worst with me she has to actually sleep on me in bed. I am now eighteen weeks pregnant with number two so this is very quickly becoming a problem. She is better with DH as she sleeps next to him in bed. We have started trying to do day sleeps in her big girl bed in her own room but when she got sick two weeks ago this stopped, she just refused and now needs us to be with her for day sleeps too.
I FEEL YOUR PAIN!!!! Seriously!!!!
I too can't do controlled crying, she is the same just gets worse and worse and it distresses both of us.
I have no idea what we are going to do i am clinging to the hope that her sleeping will improve as she gets older or that the new baby is a really good sleeper and can go into a cot.
So i wish i had a solution to give you but all i can say is hang in there and i hope that we both get some sleep eventually!!
