my daughter is 7 months she used to really well through the night and go to bed no problem. The last 6 weeks she just screams and screams when we try to put her down i cant leave her screaming so i have to take her downstairs and hold her until she drops off and carry her back up. She will then wake up about 3 hrs later screaming and will not stop until in our bed. Im so exchausted and pregnant again so i really need some advice so we can both get a good nights sleep any tips????
