announcing to 6yo daughter

Renae
I'm wanting some advice on how to tell my 6yo daughter that I'm having a baby.. she has 2 siblings to from her father which she didn't take very well from the start but is better about it now. I'm hoping for some ideas on helping her deal with it from my end because I want her to enjoy the experience.. I obviously won't tell her until we are atleast 12 weeks 😊 thanks 😘
