My 4 month old has been sleeping through the night (about 7 to 9 hours) since he was about 9 weeks old. All of the sudden he has started waking up at random times in the middle of the night. A friend told me he was just testing me and I needed to let him cry it out. Have any of your 4 month olds been doing this and what did you do?
