I am not defending Tammy because honestly, she is very punchable in the way she interacts with Asuelu and Kalani. I just think that ever since Asuelu came to the States, she along with the other sister have had to pick up the slack of supporting their mother . I get the feeling that the deaf sister contributes but not much since all the kids we saw at the house belong to her, I believe. Now, that leaves Tammy to pick the slack which would explain some of Tammy's ire toward Kalani because if she hadn't gotten pregnant, Asuelu would still be providing the bulk of support to their mother. Mom is probably bleeding Tammy dry with not only her upkeep but also the money that has to be sent back for the "church" and she is fed the fuck up!
