My DS is 7 weeks old. I am having a very hard time with wake windows. After a nap he will be up for a very long time, like teo hours or more, before he goes to sleep again. Recommended wake window dor his age is 60 mimutes. How do I get him to sleep in that time frame? I lay him in his crib and he will lay there happily for hour or more before he passes out. I have tried rocking him but he wakes when I put him down and then will take long time to fall asleep. He only does this during day. Any help appreciated!
