Telling younger children about MC

Alejandra
I'm literally on the verge of miscarrying. I have bright red blood like a period. No cramps no clotting but I feel like my baby has been taken from me. I have to wait to get my blood test levels back but I want to be prepared to tell my 5 and 6 year old who are so excited for their new baby. How did you all explain your miscarriage to your younger children??
