Night Waking

Trisha
Help! How many times a night is your 7month old waking up? I feel like mine is taking advantage of me haha. He's up 3-4 times...it used to be 2-3. Now he's waking up at 11:30,1:30,3:30,5:30 and the 6:30 or before for the day....what am I doing wrong? I feel like I'm failing miserably in the sleep department :(
