Hi Krysti! It sounds like you've got a full house!
I am also rejoining the Mothering community after a 2 yr absence.
I married my DH 11/19 of this year, we're currently ttc my #2, his first. He's anamazing stepdad/role model/parenting partner to me and my son and I can't be more thankful.
I look forward to getting to know you and everyone else on the blended family forum!
