We co-slept with our oldest but refuses to go to sleep without me beside her. What can we do to get her to go to sleep by herself in her pack n play? She screams when we put her in it and wakes up around 5am every night and screams until we get her and lay her beside us. With baby #3 on the way we just want to have her sleeping alone so we can get a little extra sleep. She moves a lot and kicks 😂😭😴
