Im kinda scratching my head, my boys 21 months old and i thought we were done with the middle of the night stuff as my boys been sleeping pretty soundly all nite since about 12 months. He has recently had a ear infection but he's been on meds for a week and no discomfort durring daytime hours.. this past week he's been waking every 2-3 hours screaming.. rocking him back to sleep has worked but this still seems odd to me as he would sleep 10-12 hours clear through the nite most of this past year.. I am making another doctor appointment but thought id run this one by ya'll .. any experience with this.
