HI,
Its going to be really hard, i agree with suzie. Put her to bed as usual (but in her own) if she cries leave her for 5 minutes, go back in and settle her back down, keep doing it every 5 minutes until she eventually knackers herself out. If she is walking it might be best to put her into a bed with a safety side on, then in a few months time you can put her in a larger bed and put your baby in the cot. we did this it saved us buying another cot. Plus abbey was put into a bed as soon as she could walk, that way we thought she would be used to a bed before baby no2 arrived, and you wont have to teach your little one into getting used to a cot, then in a few months time a bed. The only difference is the fact they can get out of bed and come to you. Abbey still takes about 20 minutes to settle down at night but as soon as she opens her door she is put back into bed and all we say is its bed time now abbey, give her another kiss, her beaker of milk and lie her down again until she goes to sleep.
