Suddenly I now have a dd who is waking 3-4 times a night again (she is 15 months) shes never been a good sleeper but had been sleeping relatively well for a while from about 8pm to 6am waking once now she won't go to sleep in the evening and is waking 3-4 times in the night screaming the place down. At about 5am I usually give her a bottle which will keep her quiet until she finishes it, sometimes she will go back to sleep sometimes not, she then wakes at about 7-7.30am on a good day otherwise around 6am. She is also becoming very whingy in the day, her molars are half way through but I actually think the screaming is more b minded than anything but I am exhausted having not had a proper night sleep for over a year now. has anyone else experienced this, do I have to go through the controlled crying again having done it once. Probably all in all we have had 3 weeks of sleeping through in 15 months so I am VERY keen to get back to this. We are also going on holiday next week to Spain and I cannot bear the thought that it may ruin a very much needed holiday.
