Has anyone successfully sleep trained a very clingy baby? My baby is still refusing to sleep without being cuddled all night long. Tried letting her cry it out but she cries louder and louder until she starts gagging. If CIO/ Ferber method was a success, did you leave your baby to cry uncontrollably or was it more like whining? I’m wondering if I’m babying my 5 month old too much or if she’s just not ready yet 😬
