anyone has problem with toddler's sleep? my son 3 y.o. doesn't want to sleep. Make me awake until 3 am or 4 am almost every day!

maybe try don't give him nap at the afternoon cos if he don't feel tried he will not sleep well at night. Morning he will wanted to have nap. Or give him some activity like drawing and colouring in the afternoon. He will tried can sleep well at night
