Ftm need advice

Gabi • Due August 2021 👶🏻
So I'm a ftm and my s/o isn't a first time dad he has a 5 year old son . But he thinks he knows what's best for my daughter when he didn't even want her in the first place . He said o don't know best because I'm not even a mom yet . Point being I don't want my baby girl to have a pacifier but he does .
