He's almost 7 weeks old and we just got back from a vacation. While we were gone he didn't have a crib to sleep in and he slept in his car seat for the most part. I know that's not good but we didn't have a lot of options. Now that we are home, he will only sleep for half an hour at a time in his crib. If he's in his bouncy chair or his car seat he sleeps anywhere from 3 to 6 hours. How can I get him to sleep in his crib again and still get a little sleep myself?
