RE: Terrible sleep issues
Traci, what you describe is very normal for a 4 month old. My DD fell asleep nursing until she was almost 6 months old. And even then, it wasn't until she almost 8 months old that she would do it consistently. Some babies fall asleep on their own at that age, but I think it is the exception rather than the rule.
I think you need to forget what others are saying and follow your instincts. Listening to your MIL, etc., is only going to drive you crazy. Believe me, I've been there! It is VERY hard to be out and about with a young infant, and the more you can stay home and get a routine established (especially without a critical audience), the happier you will be.
Good luck!
