My little girl has been awake since 6am. I've tried to put her down a few times and she's ok for a few minutes and then she just screams. I've tried settling her in her cot, picking her up and comforting her and then putting her back down and nothing is working. She is just screaming and that screaming goes on for ages afterwards while I try to settle her down. This happens day after day - I struggle to get an hour or two of broken sleep out of her every day.

She has colic/reflux so I know that doesn't help but she is so desperately overtired and she just has to get some sleep. So, when do I just give up and accept that she's not going to go down for a sleep?
