Karma is a wonderful thing! I remember my knobhead brother in law boasting about what a wonderful routine their six week old was in with sleep, put her down at such and such time, settles herself to sleep in moments, sleeps til blah, quick dream feed, back down and sleeps til whatever, it’s all in the training, just need a good routine, no reason for sleepless nights etc. Fast forward six months to child from hell who only slept for a couple of hours at a stretch interspersed with three to four hours of being actively up in the early hours of the morning. It was wonderful to see!
