Our baby is a week old but ever since he was born he has howled religiously from around Midnight until around 5am even after we have checked everything (fed him, changed him, burped him etc) Picking him up helps calm him down and he will happily sleep while one of us is holding him. Of course, he sleeps absolutely beautifully in his cot during the day. Is there anything we can/should do to get him off to sleep at night? So far we have tried white noise (failed) singing to him (failed) and walking around with him before returning him to his cot (failed) even leaving him for 15 minutes or so (failed) and burning lavender oil (guess what). We know its early days but worry about establishing a cycle. Any advice greatly appreciated.
