I'm so stressed. My boyfriend has a child from a previous relationship who's seven and lately has been going through a rough spot about her parents not being together and why she doesn't get to have a " family " soooo if timing could get any worse I'm pregnant again and I'm so scared to tell her so we thought let's have Santa tell her !! But now I'm stuck I thought Pinterest would have tons of ideas but it doesn't so I'm looking for help writing a fun letter from Santa promoting her to big sister AGAIN. PLEASE HELP ME
