My 17 month old DS wakes anytime from 6.30 onwards but he plays quietly in his cot with hig "Big Bear" (his sleep time buddy). He used to wake up at around 5.30 so we put his bed time back from 7 to 7.30pm and he nows sleeps later. We also put block out blinds under his curtains in his room as the sun shines straight into his room in the morning so I don't know which one helped but something did. He'll now wake and I can hear him "talking" to Big Bear and I usually get up at around 7-7.15 and get him up and he's happy and ready to go, go, go!
