My Oct. ‘18 baby wakes up more at night than my newborn. She started sleeping through the night after she turned one and I transitioned her to a toddler bed at about 18 months so we could used the crib for the new arrival. She transitioned well but once the new baby came, she has regressed to the point where she is waking up 4-5 times a night calling for me and if I don’t come fast enough, she is out of bed and attempting to open her door. I’m not sure what to do to help her sleep through the night or to help her put herself back to sleep. All I do is go in with her and lay down in or near her toddler bed and she goes back to sleep. If anyone has any insight or suggestions they would be appreciated.
