My son was a great sleeper all through the night. Until he turned 1. He started getting up at least once a night. Sometimes would go back to sleep after some milk (whole) sometimes be would be up for hours. We thought okay, maybe it's a regression or a growth spurt or separation anxiety, a phase. Fast forward to 14 months and it's still happening. He started daycare when he turned 1 and so I also have been back to work since this sleep issue started. I'm starting to get worn down ladies.. I know he doesn't need milk in the middle of the night, it's not like formula or breast milk. It's 3:30am as I write this and he has been up for 2 hours. Please give me some advice on how to get him to sleep through again...
