I have been trying to get my DD to sleep in her cot, she is 7 months and has been co-sleeping. The first 2 nights were good, she woke and then fed 2/3 times and settled again. Since then she will not be put in her cot, she screams and cries hysterically. Last night she cried for 3 hours, I patted, cuddled, rocked, tried music, singing etc. She settled for 45 minutes and then woke again. She just doesn't seem able to let go and go into a deeper sleep. I am in a bad place with this as I am back to work soon and am beginning to panic about it all. I also gave her calpol in case it was her teeth. She does have a cold but this doesn't appear to be bothering her too much. Any advice, comfort that this is normal behaviour. Thank you.
