DD 1 year has been in my room in a travel cot, I got her routine down to 7pm and FINALLY got her out of needing to be held to go to sleep, I’d simply put her down and she’d sleep, two night ago I put her in her own room in her actual cot and she won’t self soothe, just cries until I pick her up, I’ve tried sitting and laying on the floor next to her cot and it doesn’t work. I end up having to hold her for 30/40 minutes until she’s asleep and then put her down. What can I do please
