F.W.
Just be consistent about laying her back down if she fusses or cries. If it is just light fussing--you may just want to ride it out. If she is just playing and you know she can get back down, let her be. If she is crying or doesn't know how to get back down, lay her down, give her a quick pat and say night night or nothing at all, she'll get the point. Just be consistent and trust the process! Good luck!
