DD is 19 months...since about 12 months the more sleep she got in the day the later she went to bed was IMPOSSIBLE to get to sleep and the more she was awake in the night. so we cut down from two to one sleep. Now we are going from one to no day sleeps atall! If she has an hour or so in the arvo, she is up till 9pm or later and tends to wake at about 12 then 3 then 6. If she doesnt have a sleep shes in bed by just after 7 and doesnt normally wake till about 1 then 5.
