Hi am slowly going mad with sleep deprivation as my one year old cries the minute I leave the room. Have tried staying in her room, cuddling, co sleeping...yet she is still taking up to two hours to settle at bedtime and the same if she wakes in the night. Have had the same bedtime routine since she was 8 weeks old and the same eating and napping routine since she was six months. Was wondering if the pupd method has worked for anyone and if its appropriate to try with older babies?
