Hi
I think we may be hitting the 4 month sleep regression but I just don't know what to do about it. She has a consistent bedtime routine of getting ready for bed with songs and dim lights, book, boob, sleep. This has been working fine but the past few nights she cries as soon as I put her down in her crib and she doesn't stop until she's picked up again. She's still in our room and we don't ever leave her on her own to cry but last night I did just hold her hand and stroke her cheek until she fell asleep which took about 10 minutes maybe of her crying. She did then sleep for a good 6 hour stretch. I hate to have her crying but I don't know what else I can do because she only stops instantly if I pick her up and hold her and she'd happily sleep on me if I let her but I can't sleep that way obviously. Putting her down in my bed also makes no difference, she has to be held. I know she's still so little and I've heard sleep training shouldn't be done until 4-6 months but will I hurt her if I let her cry like that? I wouldn't leave her, just try to persist with calming her whilst she's in her bed. And if it doesn't work, if she's still crying after 10 or 15 minutes, what can I do about it?
Thank you
