How many hours total does your 9 months old or so sleep (disregard any wakings, or STTN, just the total)? DS used to sleep around 11 hours - 8pm-7am, which was perfect since we have to leave the house around 7:30am. It never failed - it's like he had this perfect internal clock that woke him up at 7am, regardless of when he went to bed.
Over the last couple of weeks, he started putting in only 10 hours and this is not working out very well for me. This means that he wakes up at 6am or 5:30 am, which is earlier than my wake up time and, of course, interferes with my getting ready process. Is this normal amount of night sleep for him? Is he permanently dropping to 10 hours? Should I then move his bedtime 1 hour later?
Re: Night sleep - 9 months old
DD has gone through phases when she wakes up 1-2 hours earlier than usual. It usually lasts for 1-2 weeks and then goes back to her old wake-up time. I've tried changing her bedtime and it had no affect on her wake-up time. You can try it, but it might not help. :-( Oh, and there is the time change coming up, so I wouldn't permantly change his bedtime until we get through that!
