please help me. i don't know what's wrong with me. i love my 3 week old so much, but when she cries and won't stop, i find myself grinding my teeth furiously and i have to put her down to restrain from squeezing her or shaking her too hard. i think she has major gas problems. i am a first time mom, 18 yrs, and i just don't know what to do and i don't want to hurt my baby. maybe i have one of those postpardom diseases or something? what can i do? i don't want to hurt her or anything, but i have problems handling my stress and anger and frustration. any suggestions?
