Baby’s bedtime


Any tips on how to have my 11 month old sleep at bedtime ? She has been having major issues only at bedtime with going to sleep. I have nightlight on for her she is fed and still screams for over 30 min we leave her to CIO. But that’s not happening ... it’s been almost 2 weeks now she won’t go to sleep at night . Any tips anyone can give me? She screams so loud and cries until we go in there and get her up again
