I am so sleepy cleaned so much yesterday, and tried going to sleep early.. but my son still wakes up about 2-3 times a night to breast feed. Thought it would get easier as they get older.. I'm just exhausted almost everyday. Is it time to get him off the boob? Maybe I'm just being dramatic because I'm tired/sleepy.
