After I have my last baby I'm tying my tubes but my family and my husband's family are so against it. My family tells me we are still young and later down the years we are gonna want more kids and then my husband's aunt is telling my father In law to talk us out of it just because she had a bad experience with it. My husband and I already talked about it and we feel it's the best option for us but I already know how my family is they talk smack when ur pregnant saying u have to many kids but then want u to keep having them. This is all getting me annoyed wit people trying to talk us out of it!!!!
