Wife & I been quarreling or arguing over many things since daughter was born.

First time parents? Life is totally different with the arrival of a baby. I’m guessing that both of you are exhausted, thus short tempered. Get help to care for the baby and you two go for a dinner break at a restaurant. Support one another in house chores and parenting. Give in for the sake of your baby. Talk when both are more relaxed and calm.
