I am going crazy!
My 4 week old lo seems to be perfect during the day. He'll nurse, and nap without a problem. But then as soon as it becomes night time- around 7ish, he totally changes! I can't get him to sleep, he'll scream and cry. The swing that used to work will only calm him for 5-10 min, neither will carrying him in a sling or the baby bjorn. He wasn't always like this! We've tried gas drops as well. He is on some oral antibiotics - could that be it?
