I feel so awful right now. Since about last month, my 4 month old has been terrible for naps. She fights it for as long as she can, thus becoming overtired and cranky, and starts to cry. Today I lost it and while trying to bounce her to sleep, I screamed in her face. I don't know why I did it but I feel fucking terrible. I've been fine the first couple of months, but the last couple I've been going downhill as a parent. Please help, I don't know what to do. My poor baby doesn't deserve that sort of treatment...
