husband and i keep fighting since baby arrived

since our baby arrived, my husband and i keep fighting about little things. being sleep deprived also adds to the tension of things. sometimes i feel like he isnt helping as much as i expect him to. he is always on his phone, texting, facebook, but so impatient with our baby. i feel so exhausted having to carry all the weight of taking care of a newborn. what do i do? we've never been like this before
