Wow that is rough. Unfortunatley as teenage mothers we have to expect negative comments and blunt ignorance. Also very unfortunatley some of that may be coming from family which makes it so much harder, such as in your case. All we can do is know that we are doing an amazing job and our children love and respect us because we are their parents and that to them, is everything. You are doing an amazing job and if you've gotten this far what makes her think you can't keep doing it?? Stay strong girl and look past the ignorance, you are doing amazing.
