Millie, it can certainly be teething. Sounds about the right age for it!
Was your DD born early? Just having gone through all of that with my LO got me to thinking that if your daughter was a few weeks early, it would put her right into the 4.5-5 month period where they go through that.
Molly was waking every hour for about 3 weeks straight and nothing I did (feed her, wake to sleep, pat/shhhhh) would get her to stop. Now she isn't doing that but she is still waking at 5 am!! :shock:
What do you do when your DD wakes so early? Do you rush in or just hold back? If you don't go to her right away, does she fuss for a bit then fall back asleep?? Molly talks to herself for about an hour then will fall back to sleep for about 1/2 hr or 45 minutes and that's it. Then she's awake and ready to play!
The daytime naps are related to her night time sleep and vice versa. I always find when Molly does 45 minute naps all day, her nights are terrible!
Another thing you mentioned was waking 45 minutes to an hour after you put her to bed? And often after that? A tip I got from another Mom on here was to try to make sure the last catnap of the day is a short one (never longer than 45 minutes) and if you are on the 4 hour EASY, keep the Activity time before bed quiet. No stimulating activities. Also, try to put her down 1.5 hours after she wakes up from the catnap, instead of the full 2 hours.
Hope any of this helps...hang in there. It will pass!! :lol:
