Since the arrival of our DD one month ago, our DS aged 2yrs 6 mths won't go to sleep until well after 9pm and wakes between 5am and 6am. He will cry 'mummy feeding baby' when anyone other than me goes to him at night and wakes screaming mummy in the morning.
He is getting chronically tired and will sleep for 3 hours in the afternoon (but we usually wake him after 2. How can we get him to sleep better at night? (We already have black-out blinds etc...) Advice please!
