So in the end I got her up, stroked her nose and she went to sleep in my arms, nothing independent about that but she went to sleep! I stayed in the bedroom through the whole nap to find out what might happen next. She woke at 35 minutes mantra crying so I ignored it. 2 months ago she used to be able to get herself back to sleep, but then we had such problems with trapped wind waking her from sleep I wonder if this has ruined any hope we had of establishing a proper routine. She then ended up screaming so I picked her up, stroked her nose again and laid her back down, she was back to sleep. Then within 5 minutes, by which time it's 45 minutes from the time the nap started, she was wide awake!! I haven't managed to resettle her, have given up trying, but she is whinging and crying, obviously still tired?!
