How to train toddler to sleep through at night ? Sttn 😴

cut down day nap. usually after lunch my lo play for 1-2 hrs. she tired, she will nap around 1plus to 2pm. she gets up at 2 plus to 4pm. By 4pm she nvr wake-up, i will wake her up. At night by 9.45pm she must go to bed, 15min of nursery video, sing song and bed time story. by 10.15pm to 10.30 she knock off. haha # Sttn
