so a few weeks ago our son got a cold and had trouble sleeping so we let him in our bed. well apparently in his mind, our bed has become his bed. He goes to sleep fine in his crib but will wake up around 1 a.m. and won’t go back to sleep. unless he comes into our room. we’ve tried taking him downstairs and sitting in the rocking but that doesn’t work. We’ve tried laying on the floor next to him and he will fall asleep but will wake up 15 minutes later and cry again. We’ve tried letting him cry and tire himself out but he doesn’t get tired. Any suggestions?
