I need any advice. My 10 month old has started only going to sleep with me in my bed. I had a great routine, which worked up until 4 weeks ago, and since, despite me doing the same things each night as before, she screams when I leave her in the cot. I'm a single mum so no help with shifts and I've lost two nights trying to not cave and battling through till the wee hours but she doesn't go off. I know they need sleep for brain development and I'm thinking of just caving completely and just popping her in with me to ensure she gets enough sleep. I know sleep regression is a common thing at this age and advice is stick to the routine, but it's not working.
