May times ba na nagiging araw ang gabi ng mga toddlers nyo, and ang gabi nagiging araw kasi ayaw matulog at all?

my toddler (21mo) is like that..before.hinahayaan ko lang sya sinasabayan kung kelan sya aantukin at madalas 12 or 1a.m.until some parents advised me not to let her sleep when she wants.so i tried to make way to put her to sleep early like, by 8 punta na kami sa bed, then sometimes i scold her if she tries to stand and play.i let her play lying down, until makatulog sya.and thank God it worked!for the first two weeks nag adjust si baby but after that kusa na syang pumapasok sa kwarto at ngyaya matulog.Ü
