So my baby has always been a pretty poor sleeper. At around 6 months I felt like I was onto something...put her to bed sleepy, she would fall asleep alone, and I would dream-feed her twice. Then, she started to wake up on her own for the dreamfeeds at those times since she had been programmed. So I would feed her when she woke up. Then we traveled for several weeks and she was back to waking 3-4 times a night. My husband and I travel a TON and I fully blame that for the fact that now, at 15 months my baby still wakes up 2-10 times a night and will only fall asleep by breastfeeding. We are currently stuck at my parents house for 3 months so I don't like to do sleep training away from home, but we haven't been in our home for 4 months already so it will be foreign to her when we come back regardless...So a week ago we tried the cry-it-out method. I was totally prepared to let her cry, and I sat outside her door the whole time and checked in in intervals like prescribed. She is a baby that vomits very easily when upset, she coughs when she cries and it makes her throw up everything in her tummy. This happens when she falls and gets hurt, scared, anything. Also when I refuse to breastfeed her for the upteenth time in the night. So after about 30 minutes of screaming I thought I was past the vomit danger zone, she was wearing herself out, although panicked, totally drenched in sweat and desperate. Then she projectile vomited all over everything. I cleaned her up, bathed her, and we had to hose down her travel bed, so she slept with me in bed for the night. I am at a total loss. I know she will vomit again if we try, plus every since then when we wakes in the night she screams rather than just babbling until I came in like before. I have not slept more than 4 hours at a time since she was born and my mental health is in the dirt. PLEASE HELP ME. I am afraid by now she knows how to manipulate us a bit to get what she wants, but vomiting is really the trump card....Thanks so much in advance for your help.
