My experience with my son who is now 20 is that he slept most nights wtih me until around 11/12, my husband has done night shift for 18yrs...now I'd sit up and watch TV and he'd be snoring in no time...by the time he turned 11/12 not sure which one exactly...I did begin to feel slightly uneasy about this situation...now I'm not completely sure of the opedial complex stuff..but I think inside all of us unconsiously we do have a part of us that perhaps fantasy's our children could also be our perfect lover??? LIke as young children we thought that about our parents...so I will say perhaps this is why we become uncomfortable...now I'm not talking about pedeophilia here...I think thats when these "nornal" abeit unconsious thoughts are disturbed..so back to my son...I did tell him at this stage I think your getting a big boy now and perhaps need to sleep in your bedroom? I didn't push him immdiately nor make him feel it was wrong..but I did plant the seed so that it would become his idea...well as I say..his 20 now and yes sleeps in his own bedroom LOLOLO!!!!!!!!! and actually his gal-friend lives here with him...( oh gosh I hear people crying LOL)......its find that healthy line between loving him but also giving him his independence and us learning to let go?....of course some may not agree with any of what I've written...and thats fine...I can only be me and do my best....
