my 2 y/o cannot accept our newborn baby.

It takes time, because ur daughter felt that her attention given was taken away by newborn. Get her involve in taking care of baby. Instill a jiejie role for her. Carry her to see the new born, and not touching the new born, it helps her to understand that she is a priority too. If the newborns cry, ask her "what shall we do now?" then carry her to newborn and say, ohhh... Baby poo poo, lets change baby diaper etc. It will take awhile. When she eventually aak u to carry baby, u say "no.. Mummy tired, don't want to carry." so she understands baby is not ur world. Slowly.. It may take months or even years depending how manja ur gal is.
