Preparing my son for the new baby

Becca

Hello! I am looking for advice on preparing my 2 year old for the new baby. Our family is like this, I have my son from a previous relationship and my boyfriend also has a 2 year old son from a previous relationship. My son is very attached to me and is used to being the baby. My boyfriends son is rowdy, loud, and has behavior issues. Do y’all have any tips on preparing both boys for the arrival of their baby brother? Thanks!
