So, I know the advice is to follow a routine, putting them down sleepy but awake in a dark room, but my 3 month old just cries if I try this, even if I know she's tired. I've tried putting her Ewan the Dream Sheep on. Occasionally she falls asleep but wakes about 15-20 mins later. What do you advise? At night she's quite good, even though she feeds to sleep. It's naps that are the problem. I don't want to be reliant on buggy/car like I was for her brother. She will sleep in the sling if I'm out and about but I really want her to be able to nap in her crib too. Thanks X
