He will nap a hour in the mornings then the of the day itl only be 20-30mins but still bes really tired an gets so cross and cranky and crys and i have trouble keepn him until 7pm for his night feed. I have tried everything from all different white noises,dark room etc but he just wont nap. Health visitor says he doesnt need much naps but hes clearly so tired. Any one any ideas to help please??
