I returned 16 days ago from 2 months in Australia. DD (7 months) has always been a bit disturbed at night but she had dropped both night feeds and was sleeping 630pm-6.30am until 2 weeks before we left to come back to the UK (so it's not purely jet-lag). She has now taken up the 10pm feed and is waking for 2 hours in the middle of the night (2am-4am or 3-5am). She chats and squeals for an hour or so before she works to a scream. Some nights she'll take a feed, others not. Last night I offered milk after an hour (I'd put the dummy in once or twice) and she refused. After another hour I ended up rocking her to sleep. She then slept to 8am.
She is not one to respond to being left and will scream hysterically if left to cry without being taken out of her cot(I have tried 'controlled crying' a few times for day naps unsuccessfully and I've tried 'ssh pat' in the bed but she gets in a total state). Also, she's now waking DS 2years 3 months.
Any suggestions? DS was in such a hard-core routine by 3 months that nothing has ever broken it! He still has 2.5 hour sleep in the day and sleeps a solid 12 hours at night - except when being woken by DD from the other end of the house! DD has been harder to 'train' and I still have difficulty getting consistent day naps from her (today she only had one nap of an hour - usually at least one 1.5 hour). She can self-settle (but doesn't always).
Any suggestions would be greatly appreciated as I am now losing tolerance and I'm a crabby old cow in the day too!
