I'm sure you have tried everything, but I will list what we do with DS:
- try the swing, I give him a paci and give him about 3-5 minutes of crying (not really crying, but he just makes unhappy noise)
-try taking her for a walk! The fresh air will help. The day we took DS downtown (we were outside all day) he SLEPT GREAT! Fresh air is great for everyone.
-last night DS just couldn't fall asleep, DH said, where is a blanket (it is so hot, I didn't give DS a blanket) DH got a blanket and DS cuddle up with it and at least STARTED to close his eyes. He didn't go to sleep right away, but it helped calm him down. And he had it over him every time I checked on him.
Let DH take care of her and get some sleep yourself (I know easier said than down!) And check back here later!!!!
