15 month old waking up same time every night

KIM

Please tell me this is a phase my daughter was sleeping through the night now over the past few weeks she wakes up between 12am and 1am every morning crying and not settling back to sleep. She gets louder and starts screaming if we ignore her I know she is tired and wants to sleep but seems like she needs one of us near her before settling back to sleep. Is anyone else going through this or should I be worried?
