Need help

Jordyn

So my baby has a mark on her cheek after her father got done feeding her, I yelled at him to stop being so rough and now that I see a mark I don’t know what to do. I feel sick to my stomach, I confronted him and he had nothing to say. I’m a young mother and a first time mother. I tell him all the time to be careful and not so rough and all he ever has to say is “well her crying gets frustrating after hearing it all day” she’s only a month old, babies cry. I don’t know how to handle the situation. Please help. TIA
