Hello. I (31F) am a step parent of a 13 year old and 17 year old, both girls. I am lucky that their moms are pretty easy to get along with. 

My husband and I are very happy. We have a string relationship with open communication and honesty. The one area in which we consistently disagree is discipline for the kids. 

I grew up in a mentally, physically, and emotionally abusive home. I have no framework of what a balanced amount of discipline is. He grew up in a very healthy home. He was rarely disciplined and turned out great.
