My baby is 6 months, is it too late for the Merlin sleep suit??? She will not sleep unless it's in our arms or her rock n play. It's been that way since the day she was born. She has outgrown her rock n play and we have tried several times to get her to sleep in her crib. We've done everything from laying in the crib with her, holding her hand while she falls asleep, sitting in the room, lullabies, white noise, leaving the room and coming back 5 minutes ea time, etc. she will not co sleep either. Only sleep in rock n play and in our arms (only if we're sitting to hold her). 🙄Idk if this matters but she is VERY clingy. She will cry if she is not being held. It has been like this since birth as well. We've tried CIO a few times and she cried for 4 hours straight. She won't even cry herself to sleep. She'll just keep crying 😂😂😂😂 please tell me it's not too late for the Merlin suit. Recently I've had to rest my hand on her chest for her to fall asleep. As soon as I move my hand, she wakes up. Is there a weighted vest I could use? Not too heavy but as if my hand were laying on top of her?
