3yr old stopped going to sleep on her own?

She's not afraid of the dark or of being alone, she's afraid she's going to miss something;-) New baby always brings new issues, your daughter is used to being the ONLY child. This may sound cruel but I'd put her to bed and when she starts her routine, firmly tell her she's a big girl and it's time for bed, stop crying. There's a change with her routine (the baby) and you either nip it in the bud now or you'll be dealing with her for months, even years. You'll need to be firm, tell her you love her, nothing is wrong with her bed, it's for big girls. Maybe read her a story before bed and play kissy face first so she feels she's getting time with you. If you start letting her come to bed with you you'll live to regret it...unless you just don't like having intimate time with your husband. She needs to understand her place in the family and that her bed is not in your room.
