Baby Sleeping

I’m at a loss. My daughter is 7.5 months old she does to bed every night around 7pm. About 30 mins she is crying. Her eyes aren’t open but she is full on crying. We’ve got to pick her up cuddle her in for 5/10 mins then she’ll go back down fine. My husband doesn’t want to let her cry it out incase she wakes up our two year old but we can’t go on doing this. Help.
