Hi honey, i think my DD is slightly higher sleep needs but we went throught the same for a few weeks between 16.5-17.5 months. Canines at their worst, we still dont have them all through yet, but we just rode it out once one cut she went back to normal, then was off again for a while then the second cut and she went back to normal again. We had 5am WU and short naps so am dreading the next 2 coming through. For the first time meds didnt seems to help, i think those canines are killers. I would be tempted to not change anything till that first 1 cuts to see if it is teeth. He is not really getting that much sleep, i know everyone is different but capping would just have made my LO worse.
Has he always been LSN?
