My 11 week old baby is going to sleep around 8pm and waking around 12:30, then 4 and won’t go back to sleep. I’m trying the baby whisperer schedule of feeding every 3 hours, activity then nap but he wakes after 45 mins sleep, he doesn’t sleep for the hour and half /2hrs it recommends . I tried for 40minsto get him back to sleep but he’s having none of it. He seems tired and when I ssshhh and pat his eyes are drowsy and he looks like he will go off and then his eyes are wide awake again. Do I persevere with getting him to sleep or just get him back up and start the routine again when he is due another feed?
