The past 2 months my 2 yo toddler has become particularly clingy and naughty with me. She is generally very independent and confident. I work full-time, so in the evenings she looks forward to my coming home, and her bedtime routine of story books and being put to bed. She has started also stalling at bedtime, wanting to read ALL her storybooks and complains when the light is switched off. Some nights I have to work late in which case she does not get her bedtime stories. She will go to sleep by herself, but wake up later in the night, 11pm or so, and cry, wanting me to comfort her. Now she is starting to do this regularly and want to come to my bed to sleep. So far we have managed to keep her in her room, but she will sleep fitfully and keep waking up and crying for comfort. She has been successfully sleeping in her own room since 6 mths, now she has her cotbed in her own room with a safety gate. I don't mind bringing her to my bed occasionally but think that she will be confused, with some nights in my bed and other nights in hers, ending up with her refusing to sleep in her own bed. I have some overnight trips coming up and worry that the night wakings and crying will get worse. I know that co-sleeping is a very personal decision, for me I don't want to undo all the independent sleep training that has been achieved so far. She has a good sleep routine, bedtime at 7.30/8pm and wakes up around 6/7AM, with a daytime nap of 2-3 hrs. THe one change to her routine is her starting playgroup in the past month. Any suggestions?
