My son has been sleeping through the night since 8 weeks , been in his own cot and having a strict routine . He goes down about 6pm and wakes around 8am but the last couple of nights he has been randomly waking up crying in the nights? I go in settle him put him back down and he cries for a few minutes sucks his thumb and falls back asleep ....
does anyone have any tips what this could be or how to prevent him waking up in the night ? Baring in mind he never normally wakes up threw the night ..
