My lo has slept through from 15 weeks, from 7-7. We took her to oz on dec 17th as my partner is from there. Although she was great on the flight she never settled the whole 3 weeks. Her jetlag was terrible and she didn't cope well in the heat. We have been home a week and a half, and although she has slept better here she is waking from 3.30/4 every day and will not go back to sleep. I am wondering if we have messed her sleeping habits going away, or if many 6 month olds change their sleeping habits. Needless to say I am disappointed and tired! Any advice, or anyone else been through something similar. Thanks!
