Thanks for the tips on darkening the room. I"ll try them. Gaby goes to sleep at around 6:30pm. She wakes up around 6:00am. We used to have her go to bed more like at 7:30pm. However, she always had such a hard time with naps, we decided to move bedtime earlier. We figured if she's such a good night sleeper, maybe she can recuperate a bit from her bad naps at night.
I know her quantity of sleep at night is great! 11 1/2 hours is nothing to complain about! She usually does it uninterrupted, except for a few random cries here and there. When she does not nap at least 3 hours during the day in two (or three) good naps, she inevitably wakes up at 3 or 4 am (sometimes more).
I usually keep Gaby up for two hours, then get her to sleep. So, if she wakes up at 6:00am, her first nap is at 8:00am. She usually starts showing sleepy signs 1hour and 45 minutes after being awake. So, I just follow her cues for that. Her first nap used to be somewhere between 1 hour and 1 1/2 hours (most likely 1 hour). Her second nap would take place at around noon. She would sleep for about 1 1/2 hours (sometimes as long as 2 hours). If she ever took a third nap, it would be a short 30 minute one just to keep her awake from 2:00pm until 6:00pm. It would usually happen from 4:00-4:30pm. She really averaged 3 hours during the day for naps and 11 1/2 hours at night, which is perfect for a 5 month old.
The problem, though, is she has been taking only 30 minute naps, which would not help her at all. Then, she would get into this overtired state, which would affect all her other naps and her nighttime sleep. During the past two days, though, she's been doing better. Not perfect, but better... What I did, I moved her bedtime to half an hour earlier (6:00pm), so she would recuperate. She still wakes up at 6:00am. This seems to be helping. So, I'll continue to try this and see if all I needed to do is get her out of the overtired state...
I'll keep you posted! Thanks for the support and advice!
