For the three nights before last night, DD (five weeks) seemed utterly incapable of sleeping in her cot on her back - woke up a few minutes after being put down and fussed progressing to screaming over and over again. The problem seems to be wind as she settles back down after being burped.
The first night I think she ended up in our bed around 3 am (she sleeps well on our chests!). The second night DH woke to me crying and walking around the room with her at 3 am and then took over burping duties so I could get some sleep. The third night I think DH eventually just decided to sit up with her on his chest all night (co-sleeping scares him) and I suggested we put her in her car seat so she's upright and she slept for about four hours
Last night we just put her in her car seat to start with and had a great night's sleep with only a couple of wakings for feeds. We've got another appointment with the osteopath on Monday, as that really seemed to help before (albeit temporarily!), but until then are we doing terrible things to her spine if she sleeps in her car seat?
