is your baby only 'sticky' recently, or has always been sticky? My boy was sticky during that age too, he's going to be 2 now and can be left alone to play on himself for the whole afternoon. I think it's during that age kind of thing. It got so bad then I even start having wild thoughts that he was always crying becos he was seeing some 'things'
what i did was if im doing my own stuff and he cries i wouldn't pick him up if he's just wanting attention. if im going somewhere not within his sight i will talk loudly to let him know Im still around (but he still cry .. ). will let him cry and cry for awhile before picking him up (also because my mum got those traditional chinese thinking babies cannot always be carried?!) imo i think if you give in everytime she cries then the baby will sort of 'take advantage' of it thus becoming more attached/dependant on you.
read somewhere that making the baby sleep alone in cot or alone takes a lot of patience, training and time. must be firm and keep trying, dont give up so fast.
at least your girl wants to sleep with you. I want to sleep with my boy, but he gets annoyed in his sleep when he can't roll as much as he wants to and kicks me off the bed. zzzz
take care and good luck
